Well heres my story. My mom gave me a sled that was crashed into a creek bank a couple of years ago. Never summarized I brought it home and with a little work she fired up, but ran really bad, and while I drove it around the house I noticed the bearing on the jackshaft was noisy. I drove the sled into the garage and changed the bearing and cleaned the carbs and now it won't start. It has a really weak spark, even with a new plug. Could the stator have been the problem before. Any advice and help on how to test the stator would be great. Thanks in advance!
