The throttle lever on this engine is giving me a fit on how to hook it up. First of all it is shaped like a half moon with no long arm to hook to and then it is so close to the carb and engine body that you can't get under it to hook up a ball linkage and if you do the bottom of the screw hangs up on the engine body and carb...the best I can come up with is a metal clevis and use a nylon pushrod....HELP I must be missing something Thanks WC
