I had to replace the sheave on top of the transmission, so after getting that far......
I tore down just about everything else. Cleaned her up. Soaked the carb for about a week in a simple green solution. (the kids had been running it without a filter) Replaced belts, got the rear tire that was stuck on, un stuck.
I'm wondering if the new belt is too big? Came from the Deere dealer and looked right, but it seems that the belt doesn't get tensioned until the shift arm is 3/4 way forward. Hmmmm. I wish I had the maintenance manual.
