Hello my name is ***** ***** am I speaking with?

It can only be 2 things. Either the carb linkages are sticking and not closing fully or the engine has an air leak. Have you checked to see if the throttle linkages on the carbs are fully closed?

How would I check the linkage and how would air get into the engine.
