My right plug burns hot and the left plug burns cold, my right carb only sucks air, the left carb blows and sucks air. I think it must be out of timing. I dont know for sure how to time it any help would be greatly appreciated.
Sounds like the time my 74 El Tigre shredded a piston skirt, the shredded parts put a hole in the case on the one side. Have you checked for a leak on the side that both sucks and blows? Maybe a gasket or seal??
