Need to get this tractor engine repaired. So, this morning I started to tear it down. Here's a pic of the inside. You can see the camshaft has the plastic gears wiped off of it. Apparently a normal problem with these. You can see some of the plastic teeth in the crankcase. Obviously I'll clean all that up, and pull the cylinder heads so I can check the push rods to see if they're better or not. But the main problem is....... I'm working on the tractor engine but every time I look over at my Harley Davidson, I want to go over there and fire it up again , and....usually I Do....LOL. Maybe I should have waited until I had the tractor engine apart before I got the Harley running yesterday. Don't worry, we'll get it all done.
