When I open up the throttle fully the motor only is running at about half.
As I release the throttle the motor slows down. I cannot get it to run on idel no matter what I do with the idle screw. The only way I get it to idle is to keep my finger on the throttle. Could this be a timing issue? It does start ok with my hand on the throttle. I have the air mixture screw out 2 5/8 turns. But I do not see much difference if any there if I try to make adjustments there. Before we rebuilt the motor we did not have this problem. Thanks for you comments. Any comments on this will be listened to.
