Missfire

Okay last week my truck straight up died. Would not fire, or even try to start. Just crank and crank and crank.
After about 3-4 days I came to the conclusion I had bad fuel. It would not light on fire if poured on the ground. I also tested fuel I had in a gas can, which did burn. So I have now drained my tank completely, re-installed it, and put in fresh fuel that I know is good. (Lights on fire).
Now the truck runs again, but its rough. Somehow I picked up a missfire. I pulled the plugs and they where gas fowled. SO I cleaned them, but they where still dirty so I replaced them. The missfire got worse with the brand new Autolite plugs, and would not idle. So I put the NGK plugs back in, and it smoothed out a bit and it idles (roughly), but there is still a miss. I replaced the plug wires as well because one read bad on an Ohmmeter. I still have a miss and the truck runs terrible, and I am now absolutely stumped as far as what to do. My truck has been out of commission for a week now, and school has stared this week. I am missing it so far due the the fact that my truck runs like ass.

what kind of wires did you replace them with? i know that once i bought some bad wires from advance auto parts (some 8mm wires) that gave me a bad idle too...replaced them with a different brand (7mm wires) never had a problem again..right now i'm running 7mm wires from napa(napa brand)

I've got Napa brand wires on it now. I swapped from NGK wires.

take your float bowl off and clean it out. Sounds like you got water in the fuel. then run some kind of water eater fuel additive.

try checking the spark plug gap with the new plugs. if a plug is gapped to far (from the manuf.) they sometimes wont ignite the fuel...causing a miss.

I rebuilt the carb after cleaning the fuel. I do need to get the fuel additive, I just can't go anywhere right now since I don't have a drivable vehicle.
Jeff all the plugs are gapped to .050.
And I do not have a stock ignition system, I am running an MSD.
