Ive taken the Carb off. Opened it up. It is as good as youd want after having been givin a new overhaul a couple months ago. It ran good till the other day when I tried to pull 2 14s with it. Then the engine tried to climb out of the tractor. I could stop that by pulling the rod going from the gov to the carb forward. I sprayed, Blaster at the entrance to the tube the cross shaft went to, and I wiggled it back and forth. it seemed to have a rough spot or catch at one end, I think when I pulled the rod forward. It will start, but vibration seems to cause it to race again. Whats your thoughts.
