The Ford Barn

We have a '29 roadster with a stock engine, including the old distributor. I have a problem that I cannot resolve. The engine is running on only 3 cylinders. And it is an ignition problem. While running, I am able to short our each plug with a std Mark 1 Mod 0 screwdriver, see a spark and the engine slow down. I get this response for all cylinders, except the fourth. I have disconnected the strip from spark plug and tested to the lug on the boat....no joy. I have tested for continuity from that lug to the post inside the boat and get continuity. I have tried three boats with same reaction. And, yes, I even replaced the rotor. What's up? Any suggestions?
