great help I had just remounted the moter and that could be the problem. although you can't move the motor at all. Still going to take it off and try again. although it seemed to have less vibration now than it did before. The spark plug boot did fall apart when I got to work after noticing it for the first time. Waiting on some of the good wire from norman to see if that helps. Could the cheap spark plug wire that comes with these chinia girl motors be the culprit?
