RPM indicator

[Ernie Martin]

Juan:

I agree with Bob. On my old '69 337D, I was initially told that they couldn't be overhauled. Further digging suggested otherwise, but it had to be done at the factory instead of my local magneto shop. If that's too expensive, do as Bob suggests and find a used one -- suggested sources are in the "Purchasing Parts" page of my backup Skymaster website at www.SkymasterUS.com

BTW, you should need only ONE magneto, the one with the RPM contacts, not two.
