magneto trouble

It is on a white industrial engine that powers my welder/generator. this thing is 6V.it has been in inside storage for about 18 months. before that it ran fine. I used it over several years periodicaly and it started every time. except for the flat battery I never had a problem with it.

what do I need to do to get the magneto working again. I am not a mechanic but I can follow directions. thanks

I know its not a tractor but I use it to fix my tractor

An impulse is the device on the drive end which stops the magneto rotation at cranking speeds, building up tension in a spring which then trips at firing point allowing the magneto part of the mag to turn quickly. This improve the rate of cutting lines of magnetic flux with the coil windings thus producing a higher current through the points.

Here's the impulse coupling on the driven end of
of the mag. You can see the lugs sticking out off the impulse coupling to the far left. Hal

This "impulse" action makes the magnet move quickly past the polepieces, inducing a good current in the coil, making for a hot spark.

If the impulse IS working, other problems could be oxidized points, not making good contact to ground the coil when they're closed, a shorted condensor, or a failed coil.
