So I need help with my son's beartracker. Need help with how the semi auto clutch works. The tracker will pull the wheels up in first after it's warmed up but driving 3rd to 5th the clutch is slipping. My question is what do each clutch do? I bought the fibers and steels on a whim. But after taking it cover off I found out the one way bearing on the centrifical clutch was bad. Now I'm second guessing myself. I ordered the one-way bearing. But what is the job of each clutch.my experience in these are limited but I was under the impression the centrifugal clutch allowed you to stop in gear without it dying. And the fibers are the drive clutches.
