Sounds like either worn valve guide seals are allowing oil to seep and drip onto the spark plugs or fuel is dripping down the intake and onto the spark plugs. When either happens it temporarily fouls the plugs until the oil or fuel burns off then they start firing again. One other possibility, if you have a carburetor, is the choke pull off is malfunctioning. When cold the choke is closed. The choke pull off opens up the choke plate just enough so the engine will run until it begins warming up and the thermostatic coil begins opening up the choke the rest of the way. HTH. -Jim


Check the resistance of the Hight Tension Leads to the spark plugs. As they get older , the resistance gets higher. Use a Multi-Meter and set the Ohm s to K Ohms. Remove the leads between the distributor and the spark plug one at a time and measure the resistance. The resistance should be between 6 and 8 K Ohms. When a lead gets to past 12 K Ohms they will definitely have to be replaced. I've found that normally the middle two leads for cylinders two and three were the problem.
