Hi Dazza,
Richard L has me sussed; I will help if possible.
I am in Maida Vale (eastern suburb).
Also, Gavin is nearby in Mandurah, and he sure knows how to party!

I know it's not really an answer to the question, but I'd just get the magneto refurbed and refitted.

Welcome aboard dazza.
 CB's advice is the way to go. Fitting Electronic ignition creates new problems for you. 
Cheers TC
