1999 Troybilt Pony-Starts up with difficulty. Runs about 5 minutes, then shuts off. Won't start until it cools down.

1999 Troybilt Pony Rear Tine-Starts up with difficulty. Runs about 5 minutes, then shuts off. Won't start until it cools down. Twice it shut off when it was tilling and it appeared that the force of the tilling caused it to shut down. IE, it struggled, sputtered and then shut off.

     Also, I have difficulty engaging the tiller where sometimes it will jump like a rocket ship after going smoothly for a while.

This tiller was abused by the previous owner. It was left outside a lot of times.

a lot of the smaller tillers have a pierced metal plate in the muffler housing, this can clog and cause problems like you describe. If your exhaust is unassembleable, take it apart and wire brush the plate then reassemble. If you have a "normal" looking exhaust pipe and muffler try taking it off and running the machine

When it shuts down... spray a little starting-spray into the carbeurator. If it runs for a few seconds... then your problem is in the carbeurator. If it doesnt run, then problem is in the spark. I had a old car once that the ignition coil would heat-up and then the car would stop running. But I would bet your problem is the little needle-jet is slightly rusted in the carbeurator.

The shutting off problem sounds like a gas problem. Check to see that the gas cap is venting and is not blocked. If the vent is blocked the tiller will run till the vacuum is stronger that the suction on the carb tube then it will choke off. After a few mins. the vacuum will be gone an it'll run again.
