I also replaced the battery terminals. They were pretty beat up and not making good connections.
Here is something I've wanted to do for all my tractors. Critter-proofing.
Both engines have seen problems with mice nests. I'm hoping this prevents any future problems. It's much harder to remove the cooling shroud on a horizontal engine vs. a vertical.
The cooling shroud is back on and I just need to install the exhaust heat shields. Then the engine can go back in. That's as much as I felt like doing today.
