Thanks TeamRush, but I think that I have found the problem. I have a sizeable fuel/intake leak at the carb to manifold gasket. And yes I set up my HEI 180* off to begin with (a long time ago) and the engine did not run at all. Just to clarify this problem only happens upon shutdown after about 1/2 to 1 hours worth of medium driving. I still think that there is a jetting problem, but that will have to wait until after the gasket fix. BTW is anyone running a weber 40mm duel carb I have one that is not being used and was told it would be better suited for this type of application.
