The engine starts right up and runs pretty fast with choke halfway out. After a short warm up I can push in the choke and the carb doesn?t flood anymore.
There is a kind of idle, but still very unsteady. There seems to be a leakage inside the carb, it goes up and down (like lean and rich) and it drips a little bit fuel.
This problem is hard to come by, because when disassembled - there is nothing to find, and when assembled - there is nothing to be seen....
:rolleyes:
Cheers,
Andy

Don't recall ever seeing an original at the ACD swap or any other swaps I have been to.

The "why" is that Auburn was basically an assembled car, using parts not always specifically designed for it. Having said that, the carb intake (esp. with an air cleaner) wouldn't clear the steering box without a bend. I have seen Auburns of this era with their carbs mounted with the intake facing forward, but then you are taking in hot air from the exhaust manifold.
My understanding is that air cleaners were not offered in 1931 and were an accessory in '32, perhaps standard on the later cars that had the Stromberg URO-2. Obviously running an air cleaner is a good idea, so I am sure most 8-98s added them early on. A friend and fellow ACD member found some heater-defroster ducting from a late 40s Ford at a swap meet that had a similar bend. With some work he made a very close replica of the original. The "can" part of the air cleaner is somewhat easier to find to find.

Ray Kuns 6 volume Automobile Engineering has a 10 page section on the Schebler model S (vol II, pp. 153-163). The S was also an updraft carb used on straight-8 engines, including (according to Chliton's) Auburn 8-90 thru 8-125. Mainly on operation and adjustments. Don't know the extent that it applies to the model T Schebler used on 8-98 Auburn, but likely similar. If someone thinks it might be useful, will try to scan.

I purchased this alu elbow and air cleaner, but it doesnt match the engine cover vent tube, coming down from the rear side cover.
Meanwhile the carb doesnt flood anymore (a sticking needle valve), but I am still looking for any kind of idle.
Will keep you posted.

It is now owned by Bob Westcot in Memphis Tennessee. You could get specs from him. It consisted of a cast Al or pot metal elbow and a small round air cleaner.

But an additional point: It is puzzling that the air intake for the Schebler is so close to the steering column that there is no room for an air cleaner. One factory photo of the 8-98 engine suggests some piece in the center of the air intake, possbily a spark arrester? You'd think there should be one. I've seen an 898 with a sort of elbow-shaped extension to the carb intake that permits a small air cleaner above the steering column. Anyone know what Auburn did about this? I don't like the notion of nothing over the opening of the carb air intake.

is anybody out there who has long time experience with driving an 1931 Auburn with the Shebler TX carb?
I am just converting my car from the previously installed, non original, but good working Carter carb to the original Shebler TX carb.
I would like to know, if anybody has some good experiences with this carb. I dont want to start a long fight with a possibly known problematic part.
Thanks in advance,
Andreas
