Check the switch.

Reset the magneto. Clean the rust off the pickups on the magneto
and flywheel - this probably doesn't make any difference, but it
makes me feel better.

Makes me feel better too ;-) I always put a little motor oil on it to help
prevent further rust.

Not sure what you mean by "reset the magneto" but sometimes the "air gap" is
off and needs to be readjusted. This is the space between the ignition
coil/module and the flywheel. If you don't have the specs for the gap size
I've gotten good results many times by simply using a thin card or a piece
of paper folded twice and spacing it that way.

Other possible causes a spark lead shorted to ground, kill wire shorted
to ground, and if it's old then a bad condensor or dirty points or points
out of adjustment. If it's an electronic ignition module and it's not
shorted to ground and the air gap is OK then I'd say it's no good unless,
for some strange reason, your flywheel magnet lost it's magnetism. Beating
on it with a hammer to remove the flywheel can supposedly do that.


Make sure you have a good plug.
