Thanks for your fast responses and valuable information. Very much appreciated.That’s what I needed to confirm what engine you have. Engine model number is LEV120 with a Spec number of 361542B. If you are positive you have a good strong battery, I would probably replace these three parts. Gear #34949A, Driver #34946 and Drive Nut #34953. You may only need the driver, but I don’t like having to take it apart replacing one part at a time. Hope this works.
