I have a shower of sparks magneto and it appears to be totally dead. Whats the best place to start?
Start by checking the magnetos retard contact assembly to see if it is operating or has fouled contacts. If the retard breaker points do not close, you may be starting with a full advanced spark that may cause a kickback. A broken wire to the retard breaker or a poor connection at the magneto may be the cause. You could also be looking at improper adjustment or a bad electrical connection in the circuit.
