When it is running and "skipping" take a wooden tongs (salad) Or a spark plug wire pliers, they are insulated against 20,000 volts, and pull off #1 plug wire from the plug. If the skip does not change, that is the cyl. If it gets worse, it is not that cyl, put it back on and gor to the next. This will ID the bad cyl. (if it starts well, just pull the wire before starting) Check all plug wires for conduction 0 ohms for a solid wire, or less than 10,000 ohms for resistor wires.
An engine with a head gasket leak can have these symptoms. Use a radiator pressure check when cold to see if the pressure drops over a two hour period. Pull the plugs and spin the starter While standing and watching. -----Out of gear and with ign off------ Watch for water comming out of a plug hole. Bad gasket is indicated if a fountain erupts. Not a big job on this unit.
