Many thanks to everyone for sharing their knowledge and experiences. I have now pretty well conceded that my flywheel assy is permanently seized onto the taper. I even resorted to cutting away the outer of the wheel to give me access for heat, and hopefully the contact points. For the next move, I have ordered an Ebay flywheel – not knowing if it is the right one, as mine has no serial No. on it with a view to detaching my brass wheel from its hub, and fitting the “new” one.
The logic is that there must be some sort of flywheel to give inertia for running the engine, but more importantly, the flywheel carries the fan and the wheel for the pull-start. Having restored some sort of flywheel, then I plan to fit some sort of external magneto. The timing of the contact breaker should be OK as this relates to the cam on the seized flywheel shaft. One possibility is to make a circuit with an old fashioned ignition coil, as on cars of yesteryear,
wit a rechargeable battery and capacitor, using only the Villiers contact points to time the spark.Idon’t think the MECO unit can be used because my “replacement” flywheel may not have the magnet in the right place, and I don’t have much access to the coil . My next task is to find a small reasonably priced 12V rechargeable battery. I live in France and stuff the comes from UK can incur customs duty as well as hefty carriage costs.
Wish me luck……… Dave
