Sounds like the spark plugs are oil fouled. Replace them. Buy a set of anti-foulers for the plugs as well. Sounds like you have worn valve guide seals. Worn valve guide seals allow oil to run down the valve stem, past the worn seal, and drip onto the spark plug electrode. The anti-fouler will shield the electrode and prevent oil from dripping on them again. HTH. -Jim
