I have a 93 750SX it has a small pin motor with 180 psi. Its all stock besides a dual Keihin 40 with 3 jets. Problem is it likes to run away. I did do a leak down and found a leak at the crankcase drain so I blocked that off. It's still running away. Ran it for about 15 seconds with my hands choking it, as soon as I take my hands off it runsaway. There is a bubble in the fuel line going from the rear carb to the front carb. I dont know if that would cause it but worth mentioning. I was thinking maybe my settings are wrong?
Pilot 45, Mid 72, Main 135
Low Screw 1 1/8
High Screw 3/4
Saturday im gonna pump the primer so fuel goes into a can so maybe I can get that bubble out and try again.
