My 100 misses. I have changed the spark plugs, wires, points, coil, rotor, distributor cap, and played with the timing; its in its sweet spot. It doesn't seem to make any difference which plug wires are on or off, it runs the same. It runs best at about half throttle, and when its cold. Misses terribly at slow and when run up. Any ideas?

Matt: Of the items changed you didn't mentioned condencer. Just could be problem. Carb could also be doing this. Don't rule it out.

I had problems once with SA, slightly different problem from yours, in that it would just stop if tractor hit a bump on road, or any other jolt to tractor. The distributor shaft was worn. This had to be machined and a bushing added. They don't have bushings when new. I just mention this one as I can see it acting differently on each tractor.
