The third cylinder on my WD doesn"t fire. I have changed plugs, plug wires,points,and condenser. The cylinder compression is the same as other cylinders. Any other suggestions?

I agree with WD45 but that should affect two cylinders - both 3 and 4. Plugs do occasionally completely fail. So do distributor caps. There could be a carbon track in the cap which redirects the spark to a different plug or ground.

I have the same problem on a Ford 901. It is #3 also but I assume that is a coincidence. I've changed plugs, caps, rotors and wires. As yours, #3 has the best compression. But it will not fire at idle - high rpm yes. I'm about to pull the valve cover and check the cam. I'm thinking it may be gettings an incomplete charge because of a flat cam lobe. It is hard to check the cam on a Ford 901 because of a lot of disassembly. A WD-45 is pretty easy by comparison.

Get some brake clean and spray it were the manifold meets up with the head, if the rpm's go up, than you will need either new gaskets or you will need to get the manifold planed

Cap or rotor could be bad or the bushings in the distributor may be worn to the point that on the one place the rotor is to far away from the cap to let spark jump the gap. Now then you say it doesn't fire but do you mean you don't have spark on that plug or it just does not run on that cylinder. You could also have a problem with a valve not opening as it should

It does not run on that cylinder. I have switched plugs and they all come out wet. I assume they are not firing.

Thats why I say a bad cap and or rotor orbushings in the distributor and even a valve that is not opening as it should any one of those can/will cause that problem

They can be rebuilt and have new bushings installed
