250cc engine rated "22hp"

[Cartinfun]

I have a Yerf Dog 3203 that I need to get running. It doesn't have an engine or TC. My Dad has a Polaris Trail Boss 250 that the transmission is jacked up and he can't get parts for. So he said I could have it. It has a 250cc 2 stroke that they say was rated for 22hp. I'm not sure how or if I could get it set up on my kart. I don't know what I would do to get the power from the clutch to the axle? That's what is sticking out the side of the engine in the first pic, right?

That is a Comet clutch. I think like model 105 or 103. Something like that. I think it takes like a 1 3/16” belt. I believe the drivens are still being made.
