Look for a correct carburetor. Your car came from the factory with a Schebeler model 'T' In mid 1932 the 8-100's came with a Stromberg URO2. The benefit of the Stromberg is that it is possible to install an air cleaner. Actually is functions as a spark arrester. This is a good thing.

Unfortunately we didn’t get the Auburn to the VCRA rally in Joplin. The symptoms persisted and we tried everything possible until the last minute. Ivor, I saw your comments and yes that first test went well but it was a flat road and two separate runs of about 7 miles. Once we put load on the engine over longer distances the issues seem to develop. Having said that, it’s possible some of our changes exacerbated the problem as well. I’m sure we’ve all been there, but you end up going in circles sometimes to track the issue down. The carb size and jets could well be the issue Randy, but that correction will have to wait until next time. Float height was rechecked, all pressures from 1.5 – 6 psi checked but no difference.

We are still entering the rally just for experience. Using Bob’s Ford 250 truck that we used to rescue the Auburn. I think we have the newest vehicle in the vintage rally, great brakes, A/C and everything!

Possibly to much fuel pressure and the wrong carb . Drop the pressure check the float height lean out the idle circuit, bore out the high speed jet. R

Thanks Randy. We are running a little rich but if we lean out too much we get very poor unitial pickup . You think we may be stumbling because we are too rich once she gets up and goes? With the 898 at 269ci we may just not have a carb that can handle it?

Hello . Are the plugs black is it loading up to rich ? By the way the BB1 is for a 213 to 235 cu inch engine not a great sub. Fuel pressure with it should probably be 1.5 lbs max. R

Unfortunately we still have the same issue. Tried the vent hole, changed the battery, rebuilt the carb (again). Runs great until it stumbles and stalls or nearly stalls out.

Site is quite frustrating to use. Amen!
Only fill the tank 95% full. If you fill it up the neck like you do on a modern car it will run out on the ground via the King Sealy atmospheric equalizer 'vent' tube.

We’ll try the vent addition to the filler tube. As you know Curt we had a suspect original pickup in our tank (see picture – yes, it’s bad). Temporarily we replaced the pickup with a new stainless steel pickup and filter that has a small vent in the top plate (no more King Sealey for now). We’ll get back to the KS gauge and pickup later.

The vent on the top of the fuel pickup is an atmospheric equalizer for the King Sealey gas gauge.
Drill a 1/8 hole in the top of the filler neck. Original caps were vented.

Mike, The gas cap is not vented but there is a small vent at the top of the fuel pickup on the tank. We had previously dropped the tank, cleaned it out and put in a new pickup with filter. The car stumbles and the engine stops, it can be restarted immediately without any problem. Sometimes we can recover by backing off the gas, or bumping before the car comes to a complete stop.

Is the gas cap vented ? Is there something in the gas tank sloshing in front of the fuel pickup? Does it ,stop suddenly as if the key was turned off or stumble to a stop? Stumble = fuel, sudden stop == electrical trouble. This is not a guarantee. With all the work you have done on fuel my guess is something else. After it dies does it restart right away?

After a few exhausting days getting the car prepared for the VCRA rally in Missouri this week we came to a dead stop literally. At this point we have everything running well except our car dies after a few minutes on the road. It seems carburetor related and I re-read John Mereness’s comments again – is the Carter BB1 just undersized for the straight eight Lycoming engine? We have tried fuel input pressures between 2.5 – 4.5 psi, opening up the main jet to the point of over richness but still it dies usually up a hill with load but even on the level occasionally as well. The carb (I/D inlet 2.125 inches) always seems to be wanting more air. Your thoughts?

A quick update on the water pump. The original shop was unable to assist further. We have been able to find a machinist locally in Springfield who has experience upgrading old water pumps with modern seals. The lip seals (thanks David & Curt) are being overnighted and the shop is confident the pump can be machined and repaired to stop the leaks. Let’s hope so. Expecting it back by Wednesday, fingers crossed.

We are going to spend the day replacing the fuel lines, 6V fuel pump and filter, adding a regulator and pressure gauge. One of the symptoms experienced while testing was an overly rich mixture and we believe there is too much pressure in the line, perhaps 4 - 6lbs. We’d like to get this down to 2.5 – 3lbs and re-tune the engine.

A run through the tappets yesterday while still warm and prior to us removing the water pump, showed 5 of them out of spec with the worst at 0.012. All have been reset to the book 0.006 – 0.008. Once everything is back together we’ll get in to our timing advance and dual points set up. A boroscope in to each of the spark plug holes reveals a clean set of valves, time to get rid of that ATF cleaning agent in the oil and replace with fresh Rotella T along with a filter change. New gaskets should help with oil seepage.

Bob successfully fitted our required seat belts, I worked on replacing our troublesome vacuum windshield wiper with a 6V low profile unit and added a signal indicator stalk along with wiring a pair of period rear lights, also required for the rally. The calibrated speedo is in as is the rally clock. Will get photos.

Still need to get in to those fuel/oil gauges. We certainly have some clear liquid in the fuel gauge but the reading is not consistent. The correct red and green fluids arrived. We have our dowel rod marked as a backup.

As a brit, I’ve finally been able to educate Bob in the art of taking tea breaks during our intense 7am -11pm daily sojourn. For an extended break this afternoon we are off to visit a local car museum and meet with the owner who has run the “Great Race” rally 3 times. He still has his old rally car in the display. Should be interesting.

Its really sad when you tell a "shop" what you want and will pay for... Only to find out you did not get what you paid for but what THEY wanted to do for you. Trust is a big thing and when you loose faith in someone its nearly impossible to get it back. Best of luck getting your water pump repaired correctly. The time crunch is the worst part besides loosing faith in a shop...

I used a lip seal for mine. I used a National 471564 for a shaft diameter of 0.625 width 0.25 and od 1.499. Sorry I didn't take any pictures. Any machine shop can clean up or make a new shaft and install a lip seal.

Take it to a machine shop and get a modern lip seal installed. It is a small one, smaller than a quarter.

After getting our water pump back, it leaks worse than before. We need a quick (3-4 day) turnaround on a proper repair or replacement if somebody has one?

Despite our request the pump was not repaired with modern seals, just repacked. After taking the car for a test drive we had a pool of water and dripping pump. It’s a shame as the test went well otherwise – 15 miles our longest distance yet, good power, strong & even braking, responsive steering, good oil pressure and cooling (despite the leaking pump), 59mph top speed (GPS verified) with a little more to come if we needed it.

There’s certainly more tuning work to be done, but if we can’t get the water pump solved then it will all be for nought at least for the Joplin rally.

Checked our fan pulley and it’s already fitted with a sealed bearing. Phew.

Can you share the fix or point to a newsletter article? I've already converted the fan hub to sealed bearings if that is the fix.

Thx

Mike, That was the request on the water pump. We don't currently have an operating gas gauge, in fact I was looking for some tips on how to service those telegauges, I did order the red and green fluids for them.

Curt, We'll look in to that - thank you. We are going through every single nut and bolt on the car. The radiator looks new, I would hate to damage it.

Is the race you are going to enter have any altitudes involved? I have found if you travel above 4000 foot your gas gauge will take a couple days to acclimate itself. The same will happened when you ascend.

After packing the water pump with waterproof grease and tightening the gland nut as much as we dare, the leak is down to a small drip. Not really acceptable for us so we removed the pump and it is off to be rebuilt, should be back on Friday.

While we were in the area, tested voltage from our generator and got a rather weak 6.85V idle, and 6.4V under load (headlights), battery reads about 6.2- 6.3V with everything off. Seems to be on the low side if we have all the electrics running and may drain the battery.

Since our purpose is to rally the car, we need better lighting. Anything we do has to be removeable so we can easily get the car back to original. The original headlights only offer 21 candle power, we can go up on the cp rating to 32/50 but these draw 3.9A/5.7A each, there are some 6V halogen bulb improvements available but they will also tax the generator with their current draw, even the 25W (4.2A) /35W (5.8A) bulbs are just too greedy for a hot 9A – 12A system. We don’t want to change out the water pump/ generator combo for an alternator and get in to all the wiring issues, besides it will spoil the look.

Not for the purists, but the answer is LED bulbs. However, you try finding a positive earth, 6V, double bayonet, 1930’s fit, hi/low beam LED headlight bulb. They don’t exist, not in the USA at least (or I couldn’t find them). But then I found this place in the UK, co-incidentally where my great uncle used to rebuild vintage motorcycles (no affiliation) www.dynamoregulatorconversions.com/led-headlamp-bulbs-shop.php
The positive earth BA15D 6V double dipper bulbs only draw 0.5A/1.0A, Can’t wait to try them, fingers crossed they may even be a straight fit. Here is a video clip from a happy customer



After staring at the amperage gauge too long, I started to look at the other gauges – Speedo good, Oil pressure good, Temperature good, however, the Telegauges (King Seeley / Hobson) don’t look to have any fluids or if they do it’s gone clear over time. I’d very much like to get these working, on a vintage rally we can’t even back in to miles/gallon to get an estimate of fuel use, the odometer is disconnected and not allowed on the rally. So, have ordered the correct specific gravity green and red fluids and the plan is to disconnect and blow out the capillary tubes from the tank to the dashboard, reseal everything except the open end at the dash board and with empty tanks/pans along with a fine syringe (bird feeders are good) refill the tubes to the correct mark. Am I on the right track or do you have any in-situ pointers for this project?

We had a bit of a setback on the tires, the fitter tells us they were delivered with tubes that have offset stems but our wheels have center set valve stems. After a call to the supplier, was told these tubes don’t exist for 17” 700 tires so they sent what they had. I found center stem tubes from another supplier.

Lastly, you might think us crazy (we do too). We entered the VCRA vintage rally in Joplin Missouri May 16th – 20th, 2018. It’s for a good cause, even if we only get the car to the start line. Burning candle power to get ready.

Colin & Bob.

A very busy week. Both Bob and I were able to work on the car.

First up, compression testing found #6 cylinder with little to no pressure – not good, we removed the tappet plate covers and assessed we had a sticking valve. We mixed in 1 quart of ATF with the existing oil, turned it over and let it sit overnight. Voila! In the morning we had pressure back. One of our cylinders is a bit low at 56, a couple are at 74 but we are within 15% +/-. Certainly could be better but acceptable for now.

Next, a carburetor rebuild. After taking it apart I honestly wondered how the car ran at all. Every part was put through the ultrasonic cleaner at least 3 times with a 50:50 mix of Pine Sol and Water. A full service was completed and now the carburetor is pristine. After adjusting the basic settings, time for a trial start up.

Nope. Five seconds running at best. After a few frustrating moments, even checking through the carburetor again, we decided to check our fuel flow. We had previously seen 3.5-4 psi but not measured fuel quantity rate – oops, just a dribble. Hmmm.

The fuel runs through a 6V electric pump near the tank and then through the original mechanical pump. We decided to bypass the mechanical pump and suddenly we had tremendous flow filling a 64oz container in less than 1 minute. So, we directly hooked up the carburetor to the 6V pump. That was it, after making some tuning adjustments with a vacuum gauge connected we had the car running nicely, we’ll make some fine adjustments after going through everything else.

Time for the brakes. We removed all the wheels and hubs, greased the nipples, checked the condition of drums, shoes, assembly and all looks really good (almost new). Decided a road test would help identify any issues best.

So, yesterday we ran the car around Bob’s farm on some pavement and it brought a big smile to our faces. Clutch was smooth, brakes were straight and strong, the engine pulled well through all the gears. We only had the opportunity to run 30mph but this was a pleasing result.

Next week we’ll work on some leaks we need to address. The water pump has a small leak, there’s oil seepage under the car so we’ll get that cleaned up and identify what’s going on, for sure we need a new oil pan gasket set so will get that ordered.

There’s a ton still to do but that’s it for now.

Jack, I like that idea – thanks.

Mike, makes sense. In fact Bob and I discussed that over the weekend and I ordered a compression adapter to work with our cars. If it helps others, the adapter is A-12405-ADP or 28-20987-1 and is commonly used with the Ford Model As of the same era. Hopefully we can get some compression figures later in the week.

Before you get too far with this motor you might want to run a compression check. No need to get it running for this and will give you some indication of the motors condition.

fire arrestor: I wound up fitting a piece of wire screen, as a temporary 'fix'. flame won't go thru a screen, I am assured by an engineer friend. meant fo post this, have gotten away from it. of course, you only need the arrestor if something goes wrong, but that's what it is for, when something goes wrong.

Eureka! After nearly 5 days soaking, tapping, heating, & cooling we managed to free up the heat riser. We were about to remove the manifolds but a mix of ATF fluid, Acetone, along with a shot of PB Blaster for good measure finally freed the riser and we can move it freely. Hopefully this will open up the door to get our engine started.

John, I agree it would be good to have an original Schebler or possibly Stromberg carburetor for this engine. Short term, we’ll see if we can get the Carter BB1 (we think 289SD) running with the car so we can test other things. We do have a service kit on it’s way.

Jack, reading about the fire does point one towards an arrestor of some type just for extra security. I’m sure if everything was working correctly it might not be needed. Unfortunately there is little room to fit one it seems.

Curt, thank you, that’s excellent news. We’ll investigate this option for the 2-speed rear. That didn’t take long, I need to find you a bigger challenge!

Carter BB1 Carburetors come in a variety of sizes as to throats and jetting - my experience is they are great to get a car running that does not have a carb, but when it comes time to do anything other than idle in the garage it is best to find what the car originally came with as new equipment. I use to see people fooling with them in their late 20's and early 30's Frankins - just not enough carb for the cubic inches to get eny high end performance - and they lost a ton of potential out of their cars.

The PM is there, I forgot to include my phone number in the first one so I sent you a second.

Thanks Curt. I was hoping we wouldn't have to get in to the manifold but we've tried everything else including heat so I guess that must be next. Have given Bob a heads up and will wait on your PM for advice.

In 1931, that car was delivered to the dealer with a Schebeler carburetor. In mid 1932 Auburn changed to a Stromberg URO2 .
The BB1 came along later and is basically a generic replacement . They run well on some cars. You will have remove the manifold to get the heat riser freed up. I'll send you a PM.

Sage advice Mike. We have the extinguisher right next to the car just in case.

During PPI the car was reported as starting, idling, running and driving well. Something got upset along the way. We aborted our start up yesterday as we have a stuck/rusted heat flap which seems completely jammed closed in the exhaust manifold. Bob soaked it over night and estimates he applied close to 20 ft lbs to the pin but it won’t budge. Thoughts? Time for the torch? Bigger fire extinguisher?

We also have the carburetor removed and wonder if somebody can ID the model from these pictures. Clearly it is a Carter BB1 but the tag plate is missing for the model number. Seems to have a cast iron top and possibly the Zinc alloy lower with a 1 ½” flange so could we be looking at a 289SD perhaps? Did I read correctly that 289’s were used on the ’32 Auburn 8-100? We expect original equipment on the ’31 8-98A was Schebler but note many cars of this era were changed to the Carter setup for reliability and performance. We are good with that as long as we can get the correct service parts.

Do folk run these with spark arrestors / air cleaners perhaps of type 90-15S or 14S? Or just leave them open to the elements?

Two great ideas Mike. for sure have an extinguisher ready and at least test the engine oil for gas contamination before starting the engine.

The GAS is is ok if you want to set the idle up a little when it is cold. Use the heat if you want, I wouldn't use it unless the weather is cold.
You really won't like it if you forget it. Pull the choke out all the way , as soon as it fires push it in all the way.

Thanks, we’ll add the backfire possibilities to the list. During transit we believe somebody repeatedly pumped the gas pedal to start the car which is not a good idea with these updraft carburetors. Hopefully, we will get every thing cleaned up tonight for a restart – max “Choke”, “Heat”, “Start” is the plan with no “Gas” (what is that for anyway, looks like it modulates the throttle linkage and overrides our foot pedal). Once she is running we can get her on to the lift and start going through everything.

A possible reason for the oil cap to blow off is a backfire. Might be too much blowby into the crankcase of gas passing the rings. I have read about this happening a few times in the past

Just a quick update as today we picked the car up (at last). On the face of things, it is pretty much as described. There are a couple of mechanical issues we need to look in to straight away 1) The car starts fine but idles very high and we have fuel coming out of the air intake which is not good – we suspect a stuck float valve, somebody changed the carburetor to a Carter at some point and it behaved correctly during the PPI and 2) we see suspect evidence of the oil filler cap being jettisoned in to space (hit the hood) at some point – assume high crankcase pressure, blow-by issues or possibly the oil pressure regulator stuck or not set correctly. Anyway, these are the immediate priorities.

Will do Curt. While the car is expected today it will go in to storage for a couple of weeks before we get to evaluate things. Hopefully it matches up to the detailed pre purchase inspection report but even that won't tell us everything. Expect many questions from us.

I imagine that you are excited about receiving your cabriolet tomorrow. After you have you have had some time to evaluate it I would be interested in your assessment. I entertained buying that car from Peter myself.
