the flex fan might be part of it but im also thinking you might have some fuel issues. do you have the thick gasket under the carb. and also look if any lines are close to a heat source.
i have an aluminum carb adaptor on the manifold to mount the edelbrock carb and stock fuel lines, hard line coming from the mechanical fuel pump to carb. it is also hard to re-start if it gets too warm but not like its blowing huge clouds of black smoke or anything.
i would like to re-emphasize that its not really running HOT by any means, but runs great when cold or cool but once it gets to normal engine operating temps it starts to act a little funny. sometimes idle speed will start to creep in neutral if its warmed up.
last summer i found it behaved a little better with the vaccuum advance disconnected but liked it hooked up in the winter.
thanks for the help so far, please keep the suggestions coming.
