Can anyone help me set my timing. The motor is pretty hard to keep idling and I have had to adjust linkage and screw my tiller screw in all the way to keep it going. Can someone help me with the proper procedure for setting the timing.
I'll try to post pics of the throttle cam and linkage later.

FR, I've adjusted the slow speed per the carb settings on here. I adjust the needle out until the engine stops coughing and then I fine tune from there. I know not every engine is the same, so there is some fine tuning involved.
When I let the engine idle, the throttle cam keeps spinning (clockwise) and the cam follower goes past the little hash mark on the throttle cam. Does that have to be stopped at the line while the tiller handle is in the SHIFT position? My cam follower stops on the bolt that holds the throttle cam on.
When I hit WOT the cam follower almost crests the throttle cam.
Don't worry about the settings on the twist grip. They are not very accurate and more for reference. You need to look inside the carb throat at the throttle butterfly. When the roller hits the mark on the cam the butterfly should just start opening. When the throttle is fully advanced, the butterfly should be fully open. Have you cleaned/rebuilt the carb?
