I agree with Pedro. It’s probably one of the flywheels, or both. If it’s off center, sometimes you can correct it with a couple of small pieces of electrical tape on the inside rim of the flywheel, assuming you can figure out which is the oblong side. It can help counterbalance the heavy side. This trick has worked twice for me before.

Again, if you can determine the heavy side, you can always remove a little material to make it balance better. Only problem is you can’t put it back. So try the tape method first.

Also check the screws that hold the cage onto the shell. Sometimes they can loosen up.

If you’re interested in trying the tape trick, I can post a couple pointers
