McCulloch Magneto

Greetings all,

Have a MAC4600 McCulloch chain saw.

Mr. Sparky at the plug doesn't want to come out.

The magneto (besides the plug wire) has two wires. One to the STOP switch and one goes to a mount on the housing.

The housing is fairly mucked up and can't quite understand what the STOP switch is supposed to hit.

Can't for the life of me figure out what the purpose of the wires are. Assuming the STOP switch becomes grounded when pushed to the stop position but only guessing.

I rotate the flywheel by hand fairly fast (half turn only). Is this enough to produce a spark?

Before I put the rope start recoil device back on (exposes the magneto) thought I'd check with you experts to learn about those pesky wires.

Hello Hopro!

The wire to the switch gets grounded when the switch is turned off. Turning it by hand won't get it going fast enough to see a spark.
