So I’ve been havin an issue with I think my magneto but it could be the engine where it will almost start then quit almost as tho it seems like the magneto cuts out when it speeds up any one know how to fix it ? Coil? Condenser points? Any suggestions greatly appreciated!

Resistor plugs and resistor wires can be hard on the coil insulation in the magneto.

Is it in time? Could be 180 out. Just a thought

I have a complete WC shop manual on line in several pieces in my directory:

One section should cover magneto timing and other adjustments.
