In open sea engine misfired on both cylinders simultanously a few minutes,
and then stoppet. Impossible to start after repeated attempts.
At last it fired on one cylinder and I was able to return to safety. Next
day it started and ran normally.
I do not want to go to sea until I have found out what caused the fault,
and100% sure it will not happen again.
What could it have been? CDI? Pulser coil? Moisture?
Anybody know this ignition failure pattern?
