I am so thrilled!! I had low compression on two cylinders so i tried to find someone to work on my force 120 L-Drive. cuz I never did a rebuild my self. after two so called mechanics turned me away I decided to do it my self.....a few people on this site said do it yourself!!!! but I had doubts.. but it was pretty easy yesterday i pulled the moter out tore it down. I found two pistons with broken rings and cylinder walls scored up... so off to machine shop I went 120 $ to bore it out .010 .new pistons 115 each gasket kit and soon I'll be off to the races..
