I have a China 66cc engine with about 300-500 km's on it. I have noticed that I've lost power...especially going up hill. It doesn't pick up speed like it used to on flat road either. I used to do up to 40+ kmph. I wouldn't do that for long periods though. Now I can't seem to get over 32 kmph. I've adjusted the throttle, cleaned the air filter, cleaned the spark plug, checked for any fuel leaks in the line and tightened head gaskets bolts.
I'm lost now and not sure what might be causing it.
