I need to make sure of a component in the descriptions given on page 2 about Magneto action. The magneto has two sets of coils in it just like a regular coil. The primary is saturated with magnetism from the rotating internal magnet. The saturation of this coil with moving magnetic lines causes voltage and current to flow making a strong magnetic field around the secondary windings. This voltage/current is then collapsed by the breaker points opening just like a regular coil. The collapse of the magnetism in the primary induces high voltage in the secondary making spark. A mag has just as much chance of making extreme voltages as a coil system. It depends on how much is needed for reliable performance and starting. Modern mags (and others not on farmalls can have advance mechanisms on them to allow better timing, the ones on Most old tractors didn't. So the only real difference is the mag gets its electricity for the primary by generating it in the primary with a permanent magnet. Where the coil system gets its electricity from the battery/charging system. Just being very clear. JimN

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac.
