On idle I short out the plug connecter to the head by using a large insulated screwdriver. When I short out 1,2 and 3 the engine slows and is idling on two cylinders it is very evident .When I short no 4 absolutely no change . As an experiment I disconnected the plugs except no 4 and tried to start to see if it would fire with any combination of timing/throttle settings but not even a cough dead as a Dodo I remain mystified .
John still in the same place and weather ,maybe if I changed the motor this might cure it !!!
