I own a 1985 25hp Johnson longshaft and at an idle and WOT it drops a cylinder, definately sounds like an igntion problem to me.At midrange it seems okay on 2 cylinders. I've swapped coils from another, plugs are new. It just started out of the blue.I've checked wiring, kill switch, every thing to me points to the powerpack(CDI) unit??any ideas??
