I want to thank everyone for the suggestions and ideas.
I hooked up a pressure gauge today - fuel pressure was almost 10 psi. I
put in a pressure regulator and the pressure is now just over 2 1/2 psi.
I now have it set so it is running about 95% right. I think I just need
to make the carbs a little richer.
Just to follow up on a couple of suggestions. I could not detect any
gas in the floats that were originally in the carbs. I replaced them
and still had the overflow problem.
The floats are the solid plastic ones - no metal arms. I set them so a
drill bit between 1/8" and 3/16" inches (per Spit manual) would just
roll under the float.
So I think I am all set. Thanks again for all of the ideas.
