Hello Josh. My name is***** you rebuilt the carb that leaves the problem as an air leak. You are getting to much air. This can be a gasket # ***** leaking or the top cover # ***** of the carb. Is the top to the carb warped or is the plastic cover cracked? When you tighten the screws on the top cover are you snugging the screws or torqueing the screws? If the intake gasket # ***** & 12 is leaking it will cause to much air to enter the combustion chamber causing a lean fuel condition. When you cover the carb you are blocking the air flow.

Have you tried adjusting the idle jet # *****?
