[AJD] Magneto?

[George]

I saw your email.  I have found a spark tester for tractors.  It snaps on the plug and the other end goes to the wire from the mag.  Then when you turn the tractor over it lights when the mag fires.  I got them at a traveling tool sale but do not remember the name of the company.  I know they work well.  Can also tell how hot the spark is by how bright it fires. Vrry handy.
