Well part #62 ain't a belt. I don't know who's drunk. #67 is a belt or a circular snake of some kind.
Who thinks they can help?

This seems to explain it. Belt driven clutch as opposed to chain driven.

Centrifugal Clutch Explained – An Engineer’s Guide to a Centrifugal Clutch
A centrifugal clutch is a mechanical device which is used on driven rotary equipment to control the speed at which the mechanical driven shaft engages.

Is it a real CVT or just a rudimentary "gear reduction"? Never seen one configured with just 1 variable sheave pulley and 1 fixed pulley. Why not just use a jackshaft? Just wanted some theorizing.
Thanks Karttekkk, but I already understand a centrifugal clutch.

That was a useless link. I was hoping they would shed some light on the advantage of a belt driven centrifugal clutch. Easier to replace a belt instead of messing with chain links and stretched chains. Lower powered engines are probably okay with that setup.

Follow up on the jack shaft - it’s junk. I’m planning on replacing it with a chain and sprocket. The drive wheel has a 60T sprocket. What size sprocket is recommended for the engine side of the jack shaft?

Depends on what is turning the jackshaft from the engine. what's the plan there?

Is the smaller sprocket indeed a 12T?
This Speed Calculator can help as you can "enable jackshaft" and put in the values (teeth count) that will get you the speed you want.

12T sprocket.

I think this will work.
