Re: 37, 120 carb percolation problems

update! I replaced the "new needle valve" on the float with the original one after soaking it and the seat in carb cleaner for a week. It appears to be doing a better job then the "new needle valve" that came with the carb kit. The old needle valve is all metal and pointed. The new valve was flat with a elastomer insert and the seat was ridged to press into the elastomer.

I think the car is running better with the old valve! I have solved the vapor lock problem with the electric fuel pump. I took the car on about a 50 mile round trip this weekend and it performed well except I did capture some gaso in the pan I put under the carb so everything is not 100% but I am getting closer.

Tried the diesel fuel in the gaso. Waste of diesel and time. The vapor lock problem was about same but the electric fuel pump took care of the problem.

Thanks for all your help and suggestions. I am getting closer and will let you know if I find the solution.
