Okay, I have shaved and jetted with 40 pilots, 142 mains, stock needles. Also coastered and replaced the leaking petcock with a new one. She starts up and runs fine. But after about 10 minutes it just dies. Doesent stumble or falter just dies. Have to fight and fuss but im usually able to restart. During one of the times that it ran for this brief duration I turned petcock to the off position, IT RAN FOR ANOTHER 10 MINUTES. Thats abnormal is it not? Also noticed that if I disconect the carb to petcock vac line the rpm goes up. So after turning it over several times tonight to try to get it to restart I have fuel coming out the front airfilter. I have cleaned the carbs twice and was so sure that I did not have stuck floats. HELP! P.S. Consider if carbs could be "loading" up due to 142 mains with stock needle.?
