Teddy may not realize it, but the re-incarnation of GEM has two kinds of nuts available for right wheel (clockwise rotation from the PTO end) engines. Most all the 820's you will find, except a few really old one, will be this way.
They all have lefthand threads on the cranks.
Now, if you are only running a single engine, then a "plug in" starter is a very easy way to start your engine.
Most of the old Coleman starters you will find are clockwise rotation. And parts are still available. I have like three of these.
Because of the clockwise rotation, and the lefthand threads on the crank, what you have to use is a hex clutch nut with a 7/16 lefthand thread on one end, and a 5/16 righthand thread on the other end. Yes, it is kind of goofy. I made one from scratch myself during a period when these were not available.
You screw this on the PTO end of the crank nice and tight, then you screw in a 5/16 righthand thread sockethead cap screw into the big hex nut on the end of the crank. Then when you hit that with the 5/16 hex on the end of the starter, it just tries to screw the cap screw into the hex, without unscrewing the hex off the end of the crank.
You can find these on Ebay all the time.
For the flywheel side, the make a lefthand thread nut with a 5/16 hex hole on the other end. This way you can start the engine from the left side of the kart - but you deed a reverse-spinning starter..
These nuts too are on Ebay all the time.
Of course, if you are running dual engines, then belt starting is the way to go.
BTW, if you are using a plug in starter, you will probably want to get a ball-hex adapter tip. It allows 25 degrees of misalignment in any direction, and makes starting much easier. Some guy here on the Form makes and sells these, by the way.....
