Torque converter off old scooter? Questions..

[VoodooChild]

Im pretty good friends with a guy who owns a small engine shop, and he let me take home an old (probably 70s) Honda Aero (i think) with an 80cc 2 stroke engine. The engine is shot, but i stripped apart the tranny and removed the drive, and the driven portion of the tranny. The Driven portion has what looks like a centrifugal clutch on the outside, and the sliding portion that changes the ratio on the inside. I pulled the shaft and bearings that the driven part runs on for easy rigging later, but the front pulley has way to small of a shaft hole for the engines i want to use (lawn boys). How does the drive portion of one of these things work, because i would like to just find a different drive unit that will fit the lawn boy. Any recommendations on which pulley to use, or for the conversion in general?
Thanks!

They work different than a cart TQ, the belt is always moving, always engaged and the driven drives the built in cent clutch. this keeps the bike from throwing you off if you let off and goose it while moving. Part out the bike and buy proper equipment.

Hmmm, i'm not quite sure i see why this unit won't work on a moped set up. Can you maybee explain in a different manner as to why a moped with a lawn boy engine that is very similar to a scooter won't benefit from using a scooter cvt?
