Hi Micheal,

When you cleaned out your regulator, did you replace the plunger correctly? If this is misaligned, it may cause fuel dripping off the carb when engine is shut off.

Is your regulator screw flush with the housing?

Is there by any chance your engine is overheating because of in-cowl application?

When was the last time you adjusted the valves? (this may not be the cause of your problem but just checking)
