I had thought the cub was under powered but driving it around holding the throttle wide open, it has a lot more power then it seemed to. I suppose I can hit the throttle control with a little weld and then file it down or is there an easier way? Wheww! a lot of questions! but thanks for all the help. I think maybe I'm getting 'er close to right.
If you have access to an OA torch you can cut the worn part away and weld in a new strip, and then file new notches. The lever will also have two grooves worn in it that should be welded up and reshaped. (one at the bottom end) I prefer the torch for jobs like this, since it is much easier to control and can make welds that are invisible after a little dressing up.
Simply filing the notches deeper sometimes helps a little, but it will wear quickly again.
You're on the right track... good luck.
