Hi from Raleigh! What is the correct gas line pressure for my 810?

Hi Bill,
It all depends on where you measure the pressure. The only place that really counts is at the carburetor. For the needle valve to work right you want about 2 to 3 psi. Sometimes you can get away with 3.5 to 4 psi but I wouldn't try it.

Some of the modern electric pumps put out 6 to 8 psi in which case you need a pressure regulator in there somewhere.

Hi Jim,
I'm thinking my pressure may be too high. Last evening I was toodling along and the engine suddenly cut out. No coughs or shutters.
I tried to restart, nothing. Popped the hood and found gas pouring out of the carb . I couldn't find any obvious problem. This morning she started right up. I idled her for a good 20 minutes trying to recreate the problem. Runs like a charm . Figure the needle valve was jammed. Gonna install a pressure regulator as a precaution

Bill you are very lucky she didn't go up in flames. One of the members out here with a fibreglass speedster replica had a fire start under the hood that quickly spread and destroyed the whole car. He almost lost his house but was able to push the blazing inferno out of the garage which is located under his house. He put it down to a possible split fuel line.

Hi Terry, That's one of the saddest photos I've ever seen. I always have a fire extinguisher in the car.... with the understanding it may only save Lynn and me and not the car.
