There are only 6 things on that side.
Seal, seal collar ? Keyway,balancer gear ( big gear)
Primary drive gear(small gear) and a nut.
You must be missing one .seal colar? Or one of the gears.
If all are present there will be no movment at all on gears.
I don't have a parts breakdown handy. Look up the parts breakdown on line.

For some reason it says I can’t upload pictures. Says the file is too big. Anyways I took the clutch cover back off and found the Nut to the primary drive gear completely backed off. It looks stripped too.. was I supposed to put like red loctite on it?? I don’t think I had the key lined up perfectly either. Live and learn. I noticed a good amount of metal coloration in the trans fluid. Hopefully nothing too severe

How's the threads on the crank?
If good get a new nut and tourqe to spec.
Do not over or under tighten. Crank damage can occur. If it's not already damaged. Just stick a small piece of aluminum or something similar between gear teeth. To stop crank from turning so you can tourqe it
Most likely you will need bigger than that. 270 -300 maybe.you will have to plug chop to confirm.good luck . keyway still fit tight
Let us know.
Stock pilot
And stock needle. In middle position
Works with most pipes.
You ussualy want to start big on main jetting and work your way down so you are not unnecessarily running it lean.
Float and air screw set correctly?
Honestly probably not. I know the float isn’t right because it’ll flood the carb out on occasion. I haven’t even touched the carb I’ve only had it a month and had engine trouble already so that was kinda the back burner. But now that the engine is all sorted out I’m looking at the other things like jetting ect. The kid I got it from didn’t even have the pipe hooked up properly. It leaked at the head ect. Air screw is typically 2-2-1/2 turns out right?

Check this out.there are other jetting links too on the forum. Read it and it woll give you a better understanding on jetting
Before you start jetting
. Glad to hear it's up and running.What height did you set your float at?
Did you set your air screw correctly? Screwing it in richens the circuit .
Out leans it out.
The needle should be fine.is it in the middle slot? 1/4 to 3/4 throttle is on the needle and slide. I would look at the air screw.
No airleaks?
