Engine Not Running Right, Appears to be running on 2 cylinders?? Options

[LotusJoe]

I removed all the tins and blower case to clean the cylinder fins and head fins, and replaced the oil cooler seals. I also changed the plugs, points, rotor, cap, and plug wires. Put everything back together and started it up. Set the timing and the engine appears to run correctly. I got out my Raytech temperature gun to check the exhaust pipe temps at the head. Cylinders 1 and 3 run about 450 degrees at the exhaust pipe where it connects to the head. Cylinders 2 and 4 are running 140 degrees. This tells me there is no fire in Cylinders 2 and 4.

Not sure on where to start checking. I'm thinking 2 and 4 are not getting fuel? Could there be a problem with the control module in the bottom of the distributor? If so how do I check it? A few months ago I did a compression check and got 165 on all four cylinders. Engine idles fine and revs smoothly. It's on a test bench so obviously there is no load on the motor. Would it run smooth on just cylinders 1 and 3?
