lodown Posted September 13, 2010 Report Share Posted September 13, 2010 What is needle Y151 for? I pulled them out when i was changing the clip position. I have some 5N7 that i'm going to put back in. What is the differance between the two? could this be my cause of mid throtle problems, the engine seems to break up when its between 1/4 to 3/4 open?
