Dirty Mag?

This has happened to me several times with a D2 and a 212 grader and it has always cured it by simply running a match book paper through the points. Hope you have some luck. Charlie

Can I just pop the cap so to speak and do that?

Yes, the points are accessible by removing the cover and rotor.......usually takes a more aggressive cleaning.......I use a point file and check continuity to see if cleaning was adequate. Have to lift the ground wire to get a reading.
Common problem.

Thankyou, what values should I see with the continuity test?

No value involved.....just a check to see if your conducting across the closed points. Can do the same thing with a test light. They are a little weird in that the whole system is grounded and you have to lift a wire to check....usually the one landed in the upper left hand corner when facing the cover.

Folding a piece of 1000 gritsand paper and draging it through the closed points 7 or so many times may do it. I don't think you have any major problem. Charlie

Some time ago I took the mag from my 2-U in to the Cat dealer and they put it on a machine that turned the mag as if it were in use. I had done all the point burnishing and had no spark. The mag worked good after that. This climate is very damp with condensation in the winter time. Now when I have a problem, I remove the spark plugs and re attach the wires so I can watch for spark, and turn the pony with a 1/2 electric drill motor. Works great and I don't have to remove the mag from the engine. Put the plugs back in and listen to that fine sound.

Hello
I had that happen to me a few weeks ago I could get the pony running and then it would quit. Turned out to be a condensor. try that too .

Thanks all, I didn't think it could be that complicated, alittle basic maintenance and I should have it firedup, my 955 is direct start so the mag issue was alittle intimidating when I first had the problem.
