Bad engine miss

How did it run when you put it down?
It ran fantastic, then life got it the way and it sat in a Florida garage untouched for 9 months to a year. When I pulled it out and tried to start it, I put fresh gas in it. Primed carb and started for a second and died. I determined fuel pump died so replaced it, put new gas filter and changed the oil. Turned the key and started right up but with a bad miss, I pulled the plugs and 6 were black with carbon and 2 were wet with gas not oil. Pulled the plug wires one at a time with it running and the second cylinder from the front on the passenger side made no difference in the motor and that was the plug that was wet.
I now thinking push rod, lifter or valve spring. Before I pull the valve covers I’m going to do the compression's test everyone is recommending. Engine only has 1800 miles on it
