Hi May seem like a daft question but when up jetting are you looking for the jet that works best for the factory setting of screw position....i have a yamaha yn50 and am currently sorting out jets. Data sheet says my mixture screw should be app wound out 1 3/4 turns (standard set up) when up jetting am i looking for the screw to be roughly set around the same position? Or is the only way to go down the plug chop route? Thanks in advance
leave the air mix screw at standard And please do not post multiple threads about the same problem, it is easier for people to follow one thread and get to the solution.
Sorry for posting multi threads, im not the best pc person in the world and half the time i confuse myself. But you answered my question still thou. Thanks
