I pulled the shroud and helps a little but I think the drive clutch is causing the vibration, there is that spot that has a chunk broke off the outer edge of the clutch and that is possibly causing a lot of vibration. I am worried about the damage that could result, you can see the damage in the pic below, the chunk missing is closest to the camera by the dent. I might start looking for another clutch, is there any specific things I should look for?
