My TFLE cannon shot speed seems to have cut way back and comes out of the out hole much slower then when I first got the game. This is not the time between balls coming out ( I have put the two washers in under the trough and the time between balls is pretty quick) but rather the actual speed of the ball itself. Watching the ball coming out I am wondering if the out hole scoop needs adjustment. Has any one figured out what this can be? Thanks
