I have a friend that is going to be selling one. I can check into it. I am going on vacation next week, so it may be after that.

I bought the engine to put on a rupp kart, ended up not getting the kart. Now i was gonna put the 820 on a frijole style mini bike frame

That engine has a step crankshaft 5/8" with a 5/32" woodruff key stepping down to a 9/16. If you decide to inboard mount the clutch for the mini-bike I can build you a 12 tooth clutch that will be fully supported by the crank. Only thing I would need to know if the threads are left hand or right hand. Most are left hand but not all of them but the same threads 7/16-20.

I had a 3/4” od adapter machined with internal step, just have to add the keyway yet, then can use regular clutch

How will the adapter be attached to the crank? I have a couple of saw engines I would love to put on a mini.
If you use the nut on the end of the crank to attach the adapter, how will you attach the clutch?
