I finally got around to removing all my spark plugs today in order to see what they may tell me about my engine's operation. I could use some of the expertise on this board to help me determine what the plugs may be telling me. Let me share with you some background: * Engine is original, unopened, cared-for '64 425 dual quad factory setup with 133,700 miles. I've owned it for a year and half. * Engine runs well with no major leaks * The plugs appear to be incorrect. The manual calls for AC 44S. * I checked the gap and they were pretty close. I made minor corrections for the ones that were off. (I gapped them at 0.035). * No engine run-on when I turn off the key. Even after a long drive on a hot day. * These plugs were in the car when I purchased it. The previous owner's maintenance records indicate these plugs were put into service in 2006, which corresponds to 10,000 miles. Photos are below: The first two photos are labeled properly. Passenger side are here: I forgot to number the second set of photos (Driver side), but the plugs are in order (2, 4, 6, 8). Higher numbers are nearest the firewall. Here is a close up of plugs 6 and 8 Here are my observations: 1. There was a good amount of oil on the #1 plug, but not on the tip. I checked the value cover above the plug and it seemed free of oil leaks. 2. The #8 plug seemed to be the most beaten up. However, the #7 plug didn't seem to be similarly beaten up. I expected them to be about the same. (I expected them to show more wear because on the dual quad setup the first carb does all the work below 50% throttle, so I think the cylinders nearest the firewall may run richer due to their proximity to carb #1). 3. When I removed plug #3 I was surprised how little torque was required. I think it was a bit loose in the hole. 4. The other plugs seem fine If you can provide any insights as to the story the plugs are telling me about my engine it would be very much appreciated. You can see that my reading was not particularly insightful. Thank you.
Did some horse trading about a week ago, custom bike for a 1925 Dodge Brothers Coach with a 4 cylinder. I can do just about anthing needed to keep the car running if I can find parts. I have been trying to find plugs, cap, rotor and plug wires. I will also need to rebuild the carb and fuel pump system to be able to really think of the car as being reliable. Any parts numbers or contact would be greatly appreciated. Please feel free to contact me if you know where i can find any of these. (fivefour oh)2 zero4 zero1three seven
