Oof $70 any centrifugal clutches? They engage at lower rpm and are smaller. Issue with torque converters is that the 40 series is literally too long for my setup.
I have a Honda gx270, which if you are not familiar with it, has a 3/4” bore and outputs 9 HP and 15 ft-lb of torque. I need a suggestion (preferably #35 chain and is under $50) for a centrifugal clutch or torque converter.
