SUPER A - WON'T QUIT RUNNING

If the tractor is running indefinately and smoothly, you may have a malfunction somewhere in switch or wiring allowing enough current through to keep tractor firing. You did mention you heard of tractors dieseling, what you don't say is that your tractor is doing that.

Think about the evolution here, just a few short years before the Super A had it's heyday, you went to the barn in the morning, fed, watered and harnesed the horse, then you were ready to work. At the end of the day you always Un harnesed, fed and watered the horse. If you worked him hard that day you took time to brush him. You just think of that idle time as taking time to brush the horse. Why you can even do other chores while grooming the Super A.

This time spent at beginning and end of day will reap huge rewards in engine life.

When you shut off the iginition, there is no such thing as engine timing; just a spinning hot piece of iron that is getting too much fuel.

Slow that idle down and make sure you've got the throttle closed when ya kill 'er.
