eBay flywheel/magneto assembly works!

[JoeShields]

Took a chance on an SJM style (Mark I) flywheel/magneto assembly I saw on eBay. Rather than tear it apart to test coil and condensor, I just cleaned it up and slapped it on my 40-, set the points and gave it a spin. It started right up on the first pull and sounded stronger than ever (may be wishful thinking). The base plate is much tighter than the one I've been using, which was pretty wobbly. I think I'll leave this new one on and package up the original as a spare.

I've used copper foil between the crankcase and flywheel base before. Keeps continuity happening. A wobbly base affects the points gap. Copper foil available from art supplies that cater for leadlighting.

Thanks! I'll look for copper foil. I tried wedging gasket paper in there, but it just wasn't durable enough. The wobble affecting points gap may explain why I think the new flywheel/magneto base makes my 40- sound stronger... the wobbly one may not have been firing on every stroke. It will be interesting to see the performance out on the water next sailing season.

Freezing rain in Pittsburgh this morning.
