What's happening here is a tuning issue. You need to spend some time after the engine is warmed up and tune the engine. Your needle settings are off. A leaking carb will in most cases cause your engine to run overly hot.

A good thing to do is to seal your engine to enable you to rule out air leaks from any tuning issue you may run into.
