    This sounds like the spark plugs in cylinders 1 and 6 are fouling. This is usually caused by either low compression or bad plug wires; so I would first run a compression check. If the compression pressure in all the cylinders does not vary by more than 25psi between any two cylinders; I would install a new plug wire set. I would also replace all the spark plugs with Autolite # APP104 (which have better resistance to fouling than other plugs). But if there is more than 25psi difference between cylinder pressures; then the engine will have to be overhauled or replaced.
