I've been working on multiple trucks at the same time these days, based on parts, job time, etc... So one of the trucks is my 1964 W500 Fire Truck.
When I first got the truck, all it took was a fuel pump to get it going, so I focused on the stopping part, front brake lines and leaky Master Cylinder. So after having the brakes working great and the new front lines and MC, the truck just kept running worse and worse.
So I bought, points, condenser, rotor, cap, plug wires and plugs. Every time i went to work on it, I found I had the wrong part. First was the points, rotor and cap. Once I had those correct I went to replace the plug wires, well too short. So I tried the truck with out new wires and plugs. Still would hardly/barley run.
Well I got a set of wires long enough, but with 90 deg ends, hey they work. Went to replace the plugs, and again the wrong parts. I knew the wires were an issue based on corrosion, so I tried starting the truck again. Still no better, ran like crap.
While checking the plug wires to be sure they were on tight, I noticed the drivers manifold was cold, while the passenger side had some warmth. I pulled out the plug and did a spark check. It was wet, so it was getting fuel. Let me tell you that's not easy by your self in a truck this tall, but was able to peek between the hood and the cowl through the windshield, and no spark.
So back to the parts store to get the correct plugs. I put them in this afternoon, and guess what! The truck runs very nice. A little cold natured, but wow, what a difference!
The plugs look OK a little black, but good gap and not burnt. Only one was dry like it was firing properly. So I've learned that hard way that yes indeed plugs do go bad and not from use.
Merry Christmas,
Will
