Some of it could be the angle and the way your carb is set. Sometimes the linkage doesnt push it all the way back in. Make sure you set it up right.

Make sure that the line on top of the carb, is lined up with the notch inside the carb. if not, its not the exact size of the circle so it wont go in and out just right.

take the carb out of the engine, take the carb boot off and clean it with denatured alcohol, put the boot back on and install the carb on the engine without tightening the pinch bolt align the carb so that the linkage can pull it straight and not at an angle. You can move the ball link (where the linkage connects to the carb) around for a better position. Once everything is aligned the tighten the pinch bolt.
