Hi all,

I am the owner of a YS 140 DZ (I believe its DZ). I have it on the Hanger 9 Edge 540. I too have been having problems with the engine seeing that I bought it from a friend. I guess he had it overhauled or something from YS factory and it supposedley works now. My problem was that it would start up fine in idle then seemed to load up and stall when advancing to full throttle. I messed with low, high, and regulator settings for about 8 hours one day and still no luck. I brought it to the feild one day and some guy adjusted my "tapet" cleaerance for me and it seemed to run better, for the most part. After reading this forum, Im going to readjust everything back to facotry settings and go from there. Thanks....
