the OHV motors really are not that hard, but I guess the new ones are a real PITA. Like I suggested earlier, if you take the wheel off and the plastic cover, it gives you direct access so you wont strip the plug or the threads in the motor. I know it makes a 10 min job a 30 min job, but I would it rather be a 30 min job then a week long job at the dealership to get the threads retapped...
