Hi, this motor has got me red in the face. mainly from pulling on it. After fixing the last problem, I thought I'd clean it up and change the spark plug and now it won't run. It try to run but won't catch enough rpm to take off. It's got spark and gas, Ive check the ground, the stop switch, and even put the original plug in. Still it just sputters. Any Ideas would greatly be appreciated. Maybe one of you guys have had this problem. Thanks.........Robert
