Latest update:
Put a carb kit in and cleaned it out real good. Fired right up! I was pleased
Had to clean the carb a few more times but then it ran fine. $25
Clutch was stuck so I split the tractor and put in a new clutch, IIRC it was $170 for new plate and bearing. Also found a huge mouse nest in the torque tube. That was free.
Pulled the head and sent it to a machine shop, they checked it over and replaced the seats and matched everything up, the valves were all in good shape. $200 (bit high I thought)
Fixed the rear rim, $30. Still will need to get a new rim as it looks ugly but is usable
I pressure tested the cylinders and they were all down 30-40 psi so I ordered a new sleeve/piston kit. $325. Still waiting on this to get here.
That's it. So far I'm $500 + $750 in parts.
Paint will probably be next year though...Need to track down some more body parts
I'm happy and having fun and learning all at the same time. My wife hates the thing though
