I'm getting ready rear down my WD for a complete rebuild this winter and I found a dead WD 45 that has been sitting outside without a muffler for a few years. Definitely froze up but the owner said it was running when parked. ($200-wide front) Will the good rocker arms and push rods from the WD work on the 45?
I loaded the spark plug holes with PB Blaster, got the manifold off and also filled those holes to let soak until I drag it home next week. Pretty rusty in the exhaust holes. If it miraculously frees up and runs what, if any, damage will I do if I run the tractor awhile before I tear down the motor to replace valves etc.? Anyone ever have a similar situation where the valves actually re-seated?
