Need some quick help from you zeel guys. About to go to a cottage for a week so I need to fix this now. I just finished building my ski late last night. Cranked it over to check spark and it looked great. I just put fuel in and it fires ever 8-10 rotations. Pulled a plug to check spark and it gives a couple sparks every second or so. Doesn’t continuously spark. Any idea why this is happening? Seems weird that it worked last night.
