I just got a js 300 for free and I wanted to fix it up for my girlfriend. The body is mint and its ready for paint just want to make sure the motor is good before I paint it. When I bought it it didn't run, so I took it all apart to clean everything and to trouble shoot. The head, cylinder and piston are clean and look fine, and the crank looks find and moves smoothy. The carb was rough and reeds were shot. I have the carb sitting in a bucket filled with parts clean, hoping to clean it up. If not what carb should I put on it. And would boysen reeds, new pipe, different filter, poss k&N and an impeller like a 16 pitch make the ski better? Let me know what you guys think.
