Jeff -- You asked several questions -- I will pick off a couple easy ones and perhaps someone else will come in with some more -- get this started so to speak. B118721 through B136314 were of the 1942 production year output, so yours is a '42 tractor; early in the production year! If I were to guess, I would say your tractor shipped well ahead of Pearl Harbor! Your tractor would use the same plugs as the model H John Deere of the same period. Champion D21 is probably one of the most common plugs -- and I believe it should be gapped at 0.030 inch. For more on sparkplugs, go to the JD-H Restoration Site -- and when you get there, one-click on Elect Systems. Toward the end of that piece you will find a host of differrent plugs that should work. Be careful. If that tractor has magneto ignition, DO NOT use resistor plugs or resistance wires -- too hard on the magneto coil! I will leave the electric starting question to another. Be sure to purchase the manuals for your tractor if they didn't come with it. You can buy the ORM 2005 Operator's Manual and PC330 Parts Catalog from Deere Pubs (800)522-7448. When you call, tell them your tractor's serial number so that can verify these are the right books for you. Deere publications can be purchased hard copy or on CD -- think on the choice before you order. For a service manual, you will need to go to a consolidated book by Primedia called the I&T (JD-4) Shop Service Manual. Deere Pubs may have it, your local Deere dealer may have it too! It runs in the neighborhood of $25 to $30. The other two are usually in the $35 range. Welcome aboard. (PatB)
