Meteor Engine magneto's

[herr-pear]

I'm not familiar with these specific mags as my experence has been with aircraft. But for mags in general: first examine the points for burning/pitting. If there is light damage they can be filed smooth. Check also for continunity thru the points when closed and make sure the rubbing block (cam) really does open the points.

Check the condenser if one is present.

Some mags have a spring mechanism that 'snaps' the rotor thru the firing point at low speeds as a starting assist. If present, make sure it is not hanging up or frozen.

Carbon ring around the inside of the distributer cap?

Coil(s). Check continunity, short to ground and if you have continunity the resistance of both the primary and secondary.

And here is one that catches a lot of people. When you switch off the engine turning the mag switch GROUNDS the primary of the mag. Most people think of turning something 'off' opens a circuit. Mags are just the opposite; you close a circuit to ground. So, if the lead between the mag and the mag switch is grounded (shorted) anywhere, the mag is dead. On aircraft this lead is known as the 'P' lead.

Mechanical problem? Bearings out to lunch? Is the mag actually turning (drive coupler sheared)?

Really hope this helps. Please keep us posted.
