put electronic ignition on it. saves weight, performs better,
Iam not familiar with this engine what size is it what was its former job blower ,weed trimmer etc.
apparently the magneto is not mounted to the engine. a mount must be fabricated to hold the magneto
near the flywheel to generate a spark , it would have to be stable and solid unafected by vibrations and G-loadand it would have to be adjustable to time the ignition . it would be easyer to put a cd ignition on it , lighter and better performing too
however it would be more expensive.

Since the carburetor mounts on the nylon main housing instead of the engine on this saw, how will you mount it? I'm sure you could build a bracket and use the original rubber manifold - is that your solution?

was just on ch site,which ignition should i order.

The ones I use for under 44cc are the regular CH ignition box and I like the Bosch cap. Anything 44cc and up I use the Syncrospark version of the same ignition. Less chance for kickback on the bigger thumpers. Bosch caps eliminate the ground strap and look cleaner installed.

I make a carb adapter that fits them and eliminates the rubber boot
