i dont think it will adjust your diff as u cant really adjust a diff unless it is limited slip which i dout
but dont take my word as we do need pics
the more the better
also serial numbers of the diff or frame might help

Kinda sounds like that was your gear box drain plug, and you now have no lubrication oil remaining so the gear box is seizing up. Pics would definitely help us, but you could also just check your owners manual and probably confirm if I'm right or not.
Your drain plug might have just used common pipe-threads, but either way you could probably find a very short bolt with the correct diameter and metric thread pitch at a good hardware store. Although it might be best to just haul your kart down there on a trailer/pickup to let them confirm the correct size so you dont strip out the threads in you gear case.
Then you could refill your gear box with the correct type/amount of oil and hope no permanent damage was done. I'd probably run it for a short while with the back tires back off the ground to let the oil re-lubricate everything well before attempting to drive it.

i would assume it is the drain plug. that is bad. you will need a new one (hardware store...)
look for a place to fill it from the top. if not, you might have to take it apart and grease it with some differential grease..
wheel bearing grease works too.

Have you checked if your gear box is full of oil or empty?
If its still full, that bolt hole you found probably doesn't go all the way through and is just a drilled/tapped mounting hole that was used for something like bolting on a skid-plate or something.
But If your gear box is completely empty we could then start assuming that bolt hole may be the source of your karts "want pull' problem.

get a peice of wire and push it up the hole
if it stops then it is just a tapered hole but if it keeps going then it is a drain
also if it is a forward reverse box u should disconnect the linkage going from the box to the driver and and get a mate to stant behind u and push the gear box into gear
if it dosent take off then i cant help but if it dose then the control that the driver uses to select a gear isnt pulling or pushing far enough and not going fully into gear
so kinda like riding the clutch in a car

Gear box
Ok I finally got a picture of the gear box to post on my pro.
The gear box is upside down in the pic so at the top right is the screw i'm talking about. you can see the drain srew on the top middle of the gear box and the adjustment? screw is just to the right of that. I hope this helps you and me.

Your right JERH, that does kinda look like some type of adjustment.
When you stick something small in that hole, does it seem to go all the way through into the gear box? (did oil ever leak out of that hole on yours?)
I'm just wondering because maybe your gearbox is a slightly different year/model than that pic and never had anything installed in the hole. In that situation the threaded hole might still be machined into your case, but just not drilled all the way through the housing. (see what I mean?)
Have you been able to find any Illustrated-component pictures of your gear box? Or anyone that even sells replacement parts for it?
If so, they'd probably know way more about this matter than anyone else here on DIY.
If you google search the net using your gearbox type, and then also enter the search term "problem" or maybe "adjustment bolt", you might just find lots of other guys on other kart forums having the same exact problem as you, and hopefully info how about they repaired theirs besides just replacing the whole gearbox

ander, the screw was attached to like a small band inside the gearbox (i took my old gear box apart) i dont know what it does but it looks like im gonna have to take the gearbox back off and crack it open to get this screw threaded back in. the band has a threaded hole in it for the screw but i cant move it for enough through the hole to get it lined back up. If this has nothing to do with the diff. wht else could cause my kart not to pull when the wheels are on the ground?
