The larger one has a centrifical clutch not a comet style clutch! It had a v belt to a driven pulley that was bolted together so it did not open up as it should! So the short of it it was only 1gear. I have ordered a slew of new parts for it, series 30 torque converter, jackshaft,gear for jackshaft and a new 30 series belt. The clutch that was on it looks like a typical one used on a mini bike that the chain attaches to but used a belt.
