Probably the best lades are made with marbain steel https://www.fisherbarton.com/products/turf/marbain/

If this is a flywheel magneto engine and not battery try opening and closing by a couple thousandths each side of .020. Kohlers a picky about timing between the magnets/coil and points. Just a couple thousandths will make a difference.

this one is a little higher than than 7.5:1

This tester works good for small engines

In the summer of 1974 i worked at a small airport as a ramp tramp in the maintenance shop. I changed lots of oil in lots of small planes. Most didn't have a filter but rather a fairly coarse screen that might stop fine sand. I asked the head mechanic why no filter. He said dirty oil under...
