If you find yourself with a stuck centrifugal clutch, there are a few things you can try to get it unstuck. First, make sure that the engine is off and the clutch is cool before attempting any of these methods. Next, try gently tapping on the outside of the clutch with a hammer to see if that will loosen it up. If that doesn't work, you can try using a pry bar to carefully wedge between the clutch housing and flywheel to see if you can separate them that way. Finally, if all else fails, you may need to use a drill to create some holes in the clutch housing so you can bolt it back together once it's been unstuck. With any luck, one of these methods will help you get your centrifugal clutch unstuck and back in working order.
