1920 Fordson Problems?

Electrical: The Fordson uses the same ignition system as the Ford Model T - unless someone has added an aftermarket magneto. There is a generator built into the flywheel to supply power to the ignition system. There are magnets on the flywheel itself which can become weak.

Mechanical: Pretty simple. No oil pump, water pump, nor brakes to worry with. Don't try to pull it to start it. Final drive is a bronze worm/ring gear that can be ruined with one good tug. Unless the head has the words "high compression" cast in the top, the engine will roll through compression fairly easily. Manifolds cracks are common as are missing carburetors and vaporizers. Different makers supplied manifold systems so you will need to know what you have when getting parts. Kingston and Holley are just a couple of them. Air is filtered by a thing Henry called an "Air Washer." That is the cast iron tank looking thing between the engine block and the steering gear. Inside is a tin float that most likely has rusted and will choke off the air supply to the engine when it is down.

In all, it is a fairly straightforward machine. Parts can be expensive so budget accordingly. Post back when you have specific questions. Best wishes and enjoy your Fordson.
