I have a 2 cylinder Wisconsin engine with a Wico magneto on it. I have taken it apart and cleaned everything, including the points. The coil checks okay with an ohmmeter and I replaced the condenser. The problem is that it has no fire. I talked to a guy who rebuilds magnetos at the Old Threshers Reunion this weekend, and he said my magneto should never have a problem with the magnets, even though the magnet feels pretty weak to me. I think he really wanted me to spend $175 for him to rebuild it for me (No thanks). I have re-arranged the internal wiring of the mag so that I can put voltage to it externally, and the spark is very hot (temporary rigged setup, about 6 volts input). Here"s my question: What should the input voltage be in order to keep from burning the coil? I figure a simple universal ignition resistor may not limit the current enough. Anybody have a "knowledgeable" recommendation? I have some knowledge of Ohm"s law, and can figure the voltage/current for the unit, so a fairly technical answer doesn"t scare me too much. Good Luck and God Bless, Tommy

Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
