Oh, about pulling the magneto rotor on this bike - I found something odd.
Unlike the Puch, the Solo has the mag installed on the right-hand side of the engine, and it rotates clockwise. On a clockwise-rotating flywheel, I expect to find a lef-hand threaded nut - as the direction of rotation would tend to loosen the nut otherwise.
Not on the Solo.. the magneto nut is a standard right-hand thread. I'm sure this works fine, but it was a little surprising.
I also measured the resistance of the plug cap, expecting to find 5-10K ohms - but it measures almost exactly 1K ohms. Don't think I've ever seen a 1K plug cap in my life. Is this correct?
