I have this 200 and for some reason I just cannot get it to run right. It is just slow to rev / lack of throttle response. It will spool up after holding the throttle wide open for a second or two, but the throttle is just not as responsive as it should be. I went through the carb, checked the fuel line, and the crankcase pulse line, as well as adjusted the carb, all with no success. Do any of you have any suggestions? thanks
