I have a 68 Cub Cadet 125. I'm trying to use it as a snowblower tractor. It has low compression, I removed the head and there are no visible signs of damage. I try to start it and it backfires out of the carb. Once started it will run just fine. If I put load on it, it will squeal and white smoke will come out of the breather cover and the motor will eventually overheat and shut off or squeal and die. I originally thought this was oil burning, but that is not the case. The oil remains clean the entire time. I am starting to think it is a bad piston, but have heard that it may also be a bad head gasket or exhaust valve. I'm not sure.
