Re: Speeditwin Magneto

[George Emmanuel]

Nice job! The original mag handle bolted on the underneath of the mag plate. The diagram Garry showed is for the later version but the principle is the same. The early one like yours has a tab on the advance lever and an insulated "button" ( more like a rivet with insulating washers around it) that the wire coming from the coil attached to such that when you depressed the tab it grounded the button thus killing the spark. The mag plate you have is the beginning of the transforming that changed from the 1920’s style to the 6039 Speeditwin.

I love you creativity!
