 Kevin, you didn't say what type (model) Wico mag you are working with. It doesn't make any difference on the failure mode, but could on the parts to repair it.
~It sounds like you have a broken impulse spring [#3] as that is the usual failure when the mag quits snapping. (there could other reasons but that is the most likely).
~When replacing the spring; pay attention to the direction the old one was wound, then lightly oil the spring, then clamp the drive cup (#2) in a vise & wind the spring inside it (be careful not to nick the spring with a screw driver or pliers when installing) then pull the inner spring end out slightly, then install the cup (#2) on the mag so the spring inner end engages the notch in the drive cup spacer washers, then push the cup on, then clamp the rotor shaft (points end) [#23] in a padded vise (must have soft protected jaws), then pull the cup (#2) out until the projections clear the flange, then wind the spring & drive cup 1 complete turn (it is easier to wind it 1/2 turn then push it on, then get another hold on it, pull it out again & make another 1/2 turn), when it is wound 1 turn push the cup on, then put a little grease on the outside of the nut & install & tighten the nut.
~Click on URL below for Roberts Carb, then go to mags, if you have a Wico C or X he will have parts at a reasonable price. Deere will also have some of the parts yet. If you have an AP or other Wico & can't find parts, E-Mail me for other sources....
