Check timing. Also could have jumped the timing chain

Without commas (,) and or periods (.) this is hard to read.
But, did you check all of the other push rods to make sure that the rocker arms are tight? With loose rocker arms, valves won't get opened completely.
If timing is good, make sure firing order is correct. It's getting fuel, but is it flooded? Have you checked to see that you have a good spark?

Have you changed the plugs, wires, distributor cap and rotor button? Sounds like water got in there somewhere.
