I'm on here investigating the same problem. On going, have tried everything we can think of....still...dies and doesn't want to start...anyone?

This problem bugs me, one would think if your fuel pump is good and the filters clean, you would have a constant supply of fuel. When the engine quits pour a cap full a gas down the carb.

i moved fuel line far away from headers.put a thick gasket from edelbrock under the carb to keep the heat away from the bottom of carb.it seems to work much better.now i have to replace intake gasket, oil splashing out on back side. the under hood heat is crazy hot.i have a clothes pin on fuel line it supose to help.

Hard starts when warm, gas smell, excessive heat.....sounds like timing is way out of adjustment
