i think i may have an air leak but i have already taken my engine out and checked for leaks and sealed it (even tho i couldn't find ne). it is still acting like it has an air leak, like it is running lean but the needle settings are really rich, i have to blip the throttle all the time to keep it running, i have a new tank and all new fuel lines on it.i am getting really sick of it, it is a sh.28 p6 pro BTW, and can ne one tell me where i can get a replacement pull start in aus. and can ne one tell me the names of the "rebadged" sh.28's plz like the xtm, thanks
