It is most certainly for reverse. If that shaft did not turn counter clockwise the tranny would not have any power for reverse.
Not a go kart, but my tecumseh won't start

Then how does one go forward?
That shaft in fact drives the trans which has 3 speeds forward and one reverse.

All tillers/snowblowers that have forward and reverse, have two drive pulleys, which in turn you have two idlers and two belts. Forward drive is off the crank, reverse drive is off the cam. When in forward drive the idler for reverse is dis-engaged same way for reverse the idler on the forward drive is dis-engaged. It does not make any difference how many speeds the tranny has. Another thing, the shaft off the cam has nothing to do with the two stage, the second stage is powered from the drive for the feed auger.

All?
Not mine. I have the identical engine as the OP and this is how my machine operates.
Trans utilizes disc drive and friction disc system.
Position of friction disk on disc drive determines speed and direction.
If friction disc is to right of center line of disc drive, then machine moves forward.
Conversely, if friction disc is left of center line of disc drive, then machine moves in reverse.

There could be, but none that I am specifically aware of.

There's a bit of confusion in this thread...
* SOME snowblowers and tillers use the camshaft PTO to achieve reverse, through a combination of belt tensioning, and/or rubber drivewheels. SOME use the disk drive described above, some use a little gearbox.
*Tecumseh L-heads are very commonly found on older Craftsman equipment. They are marked Sears or Craftsman, and have a model number unique to the OEM. The internet is loaded with cross-reference info. My faithful old Tec H60 originally came from a mid-1980's Sears snowblower - and did NOT require (or have) a camshaft PTO for reverse.
*H60's are very plentiful, if you look. If you cannot fix your engine for whatever reason, source another one. If the replacement does NOT have the camshaft PTO, then re-use your camshaft and side cover from the new engine.

I completely forgot about about the disc drive ones. But their operation is not the same has the two belt, tranny drive ones. If I remember correctly the disc drive has a differential and not a tranny.

If you do, it won't be a Tecumseh. They went belly-up some time ago.

Semantics.
To my (somewhat) limited knowledge, the design appears to be obsolete.
Of coarse Tecumseh has (sadly) gone out of business several years ago.
Keep an eye on Ebay. Sooner or later it will show up.
