I have a 1989 RM80 that is running rich on the low and high end. I know the low end throttle response can be corrected with a knew pilot jet, but on my high end I'm not sure. My fuel mixture at the moment is 36:1 and I have a 220 main. I know for a fact that it is exceptionaly rich on the high end, but should I change my my fuel mixture or my jet.
