I recently put a 12hp in my 102. The motor runs great once I get it started.
The problem is the starter turns it over but slows way down at the compression point. I took the motor out and checked the compression release spring. It looks fine to me. I also tried jumping it with another battery...same thing. Could it be the timing is off? Could it be the starter? It spins fine with the spark plug out. Could their be another problem?
Any help would be appreciated!
