I'm with Dean on the carb adjustment. If adjustment is too lean, engine will stumble. If adjustment is too rich with today's gasoline, fowled plugs.
My test is with a warm engine:
1. slap gas lever to wide open throttle and back to idle. If it stumbles, open main jet 1/8 turn and try again. Repeat until no stumble.
2. after eliminating the stumble, close the main jet 1/8 turn and re-test to wide open throttle. If it stumbles, open the 1/8 turn. If no stumble, close another 1/8 turn. Re-test.
