evinrude 20 hp '76 spark on one cylinder

[jazzmen]

Hi, my motor was running fine and then it stop with no warning. I've done a few test and realised it is running on only one cylinder. Spark plugs, coils, wire, its all good. I've changed the points and condenser and still the same. Doesnt seem to have any short anywhere. Someone have a idea???

You may have missed a connection somewhere. I would go and re-trace everything and make sure all the connections are good and true. You may also check and make sure that your flywheel hasn't worn through any of your wiring, on your coils or condensors. This is a common thing, if they are assembled with wires riding too high and not tucked out of the way of moving parts.
