I agree about the mag. Mine got weaker and weaker. Used to take extreme choking, then mostly open choke afterward to start; and a lot of adjusting on the advance to find a sweet spot. Was easier to just pull-start it.
When I first got mine, the valves were stuck open. Had to take off the side cover and work them loose.
Your fuel system may need cleaning out. The oil bath aircleaner may be pretty bad. They used to use live steam to clean them out.
The bottom of the oil pan may be full of condensed water vapor, and should be drained. Probably same with rear end gearing.
Make sure you've got good antifreeze.
In my case, the front wheel bearings were dried out and needed repacking.
You'll probably need a real long starter-to- battery cable. Luckily these tractors used 12 volt systems. You'd better find out which post is ground, I've forgotten, just now.
I also occasionally have the starter bendix jam the flywheel gear. You have to rock the tractor or work with the hand crank to loosen it up. Sometimes, the starter has to be partially unbolted. So don't automatically assume the engine is stuck.
The other thing people warn about is to keep the parking brake off. To let it drag will ruin it.
A weakness is the thrust bearing in the governor. Used to be available new, but don't know any more since the source died.
Also, the exhaust manifold should have a U-shaped pipe section and an upward pointing muffler. I don't have them. I'm afraid of breaking the manifold trying to get the studs out.
There is only one source for the front tires, 6.00 x 19. Get your order in. You may want to get your rear tires drained of fluid and clean up and repaint the insides of the rims. The rear tires are a fairly common 12.4 x 36.
