New Caber rings and I opened up that stupid little exhaust outlet on the muffler. First gen m-tronic. It runs good once warmed up but it takes a few pulls to start. I did not re-build the carb. I had a few of these and was short a top cover and clutch cover for this last one. I put covers from another one on it and ran two tanks through it. Everything works and it runs oils, and brakes the same as the others did. $275. If you have a set of covers I would be interested in buying those too.
