The mag on the F-20 had an impulse. It would make a pretty loud click or snap sound every half turn of the cranke. Is what this actually did was there was a dog in there that would catch something and stop the mag from operating briefly, and when the dog released it (spring loaded I think) the mag would play catch up, moving faster untill it caught up. This aslo helped delay timing when starting. When the tractor reaches a certain RPM after starting, the impulse will be inactivated and wont make any noise. There is also a spark advance. This is adjusted by moving the cap that fits over the points. This was originally controllable from the drivers seat, but if linkages and what have ya are gone, then you will have to adjust this by rotating the cap. If timing is correct, the spark adjustment should be down for the run position, all the way up to kill it, and part-way down to crank start it. The only way to get new sleeve and piston is to get a hole set. That means all 4. Not sure about trying to fix the old one, you will just have to see what you can have done with it. Then that leaves used parts. I had one like you, but only I had a broken sleeve. The rest were good. I founf an engine that was froze, and I took it apart, and took out a piston and sleeve that was not froze. Most froze engines are not ussually froze on all 4 cylinders. Find another froze engine and you could very well find some good cheap internal engine parts.
