I have a Cub 1450 w/a K-series 14hp Kohler that I just replaced the points. Setting them to .020" causes excessive spark knock/ping when the engine is fully warmed and under load. I reset the point gap to .013" which eliminates the ping. Starting is slightly harder w/the reduced gap. So my question is, which component is most likely worn that is causing the timing to be so far advanced with the points set at .020"? I'm hoping it's the push rod (cam to points). Or am I mising something else?
Any advice would be appreciated.
