The number on the chain usually refers to a particular size, pitch and width of some of the chains components.

You'd need a small sprocket, preferably some sort of a clutch, for the engine and a larger sprocket for the wheel. I don't know much about what's available for those small engines, but I'm also interested in finding out. Hopefully someone else will add more to this.

Yes, assuming you can find on that fits on there just right.

Yes, but that's what the clutch is for, it'll rotate freely as long as the engine isn't revving high enough to engage.
