I have been fouling plugs all the way around and had been pursuing the possibility of leaking intake gaskets. Before pulling the intake and resealing I ran a full leak down today as I was nervous about the bad experience I had with my 660 carbs and feared I washing out the rings.

On my leakdown gauge all my numbers fall well into the "Low" scale on my gauge. 40% is the start of the moderate leak scale. I only have 119 miles on the engine so I am thinking that my best numbers indicate that the rings in those cylinders have seated and the double digit numbers indicate cylinders that have not yet seated.

If the new intake gaskets don't stop plug fouling then I think I will look again at my MSD distributer-rotor phase maybe. I have had 2 ignitions, 3 caps and 3 sets of wires. Running cheap Autolite 45 plugs for now until I get this sorted. Perhaps Autolite 47 would help. The car idles pretty good but the plugs drop out fairly fast when running down the street.

Someone also mentioned running a ground cable from the engine directly back to the battery.

Open to all feedback.

Thanks Ray
