If anyone can help me, it would be appreciated. I have a YS 140 FZ that I just had to put a new cam gear in because it stripped. It does not run real good now. There is actually fuel coming out of the carb as it runs. This it was doing before the gear change. Question. Off one pinion on the gear, valve not closing all the way. Too much pump pressure? What should I look for first. It still turn up 7,500 rpm on the ground with a 15X12W prop, but does not have the power it once had and runs rought, cuttion out at times. What shoul I look for? I think some of the intake O rings are not sealing very well either.
