I am having problems with this motor popping at idle, I completely rebuilt the carb with a OEM rebuild kit and cleaned out the water sediment bowl. Any suggestions would be appreciated.

Thats usually means its running too lean, plugged jets in carbs, carbs out of sync or air leak in intake manifold or crankcase.
