Question: do you need a clutch with a centrifugal force torque converter?

I've been thinking of using a honda 4 stroke for a build. I've seen the torque converter on the motor but couldn't tell if they had a clutch or not...

These generally have a centrifugal clutch inside of them.

On a torque convertor, you actually got 2 clutches, a drive clutch is the 1 on the engine. Then there is the driven clutch, it's the bigger of the pulleys/clutches & your chain is hooked to it.

Ok, so when you're at idle the chain isn't engaged, until there are more rpms?

Yes just like a centrifugal clutch. More rpm is needed for engagement to move. At a stop, it will just sit there & idle & not move. Then when you give it throttle the clutches engage & you take off riding.

they actually just have a bushing that rests on the shaft and lets it freewheel when the engine rpms are low (due to the belt not being engaged to the walls of the torque converter) once RPM increases the weights get thrown forward (or in this case, sideways towards the engine case) and then the pulley grabs the belt and then you have engagement.

works the same as a scooter transmission, just designed a bit differently to accomplish the same thing.
