On refitting the throttle and choke assembly I cannot get the throttle to remain on minimum rpm. The bottom govener arm seems to drift up and revs increase.
I bet a whole lot of stuff. If your engine is like the FJ180V, Kawi has several pages of how to setup the throttle/choke linkage one must follow to a T. If not the linkage will not work proper.
Recommend downloading the manual for YOUR specific engine and read it several times.
