Dead on 2 and 4

If you've got compression, spark and fuel, the cylinder should not be dead. Since you have compression, unless as mentioned above, you have a rag in the intake, I doubt that fuel is the problem, so....
I would start with either new plugs, or plugs that you know fire, cause they were in other cylinders of your engine. Then, I would either swap some wires from another cylinder onto 2/4, or new wires, and see what happens.
My bet is still an electrical problem.




(But pull the carb, and look for a rag, lol)
