I"ve downloaded the owners and service manuals from Kohler"s website and also tried varying the point gap. Too far either way at open throttle with a load(PTO engaged) slows down RPM and if I go to far either way it starts misfiring.
I moved the points to the smoothest-running highest rpm it would get to under the pto load and locked them down. Still no difference.
Is varying point gap the only way to adjust timing on these? It sure acts dead like a car engine does when it needs more timing.
A last note- went to mow after I"d posted and while it was really warm I was messing with the points, I noticed quite a bit of blowby coming out the breather cover(assuming that"s the cover under the carb that covers the valvesprings). It just might need rings after all.
Anyone know what cranking compression should show on a compression guage on one of these? I didn"t see that spec on the kohler website.
