I picked up the Kohler 20 and since the wiring is much simpler, I decided to see if I could get it going the other day.
It had "Good" written on the starter so I expected the starter should work.

To my surprise, I was able to get it to turn over and it actually popped a time or two using the ether.
I took the cover off and found it had signs of prolonged use in a very dusty environment, and was most probably overheated.... and mice had used it as a condo.

It also had a head bolt that backed out far enough to hit the flywheel.

It turned over, but would "stick" at TDC on the compression stroke.
Research on the interweb says overheating can cause the exhaust valve guide to be pushed out, and that affects the operation of the compression release - causing a slow crank speed when starting or "weak starter/low battery" like symptom.
I don't have a picture of it, but the exhaust valve guide was definitely pushed out a bit more than the intake side.
After watching a couple of videos on repairs on the Courage 20, I used a socket and pounded the exhaust valve guide back in a ways, but hit it one time too many before checking my progress and when I checked, it was now 2mm shorter than the intake.

Anyone here have experience with the Kohler command 20 ?
I expect it may have carb issues as well.
Is it worth another $25 in parts and the effort to rescue?
