Re: Vapor lock percolation?

You have done a lot of what normally helps. Next thing I can think of is the float levels. Have you checked them? Also you can put a clear filter in it and see if the fuel is boiling. When you have the top off check the accelerator pump. Also set the fuel pressure at 4 to 4 1/2 psi. You need a pressure gauge in the line just after the regulator to ensure what you have.
