thats what gas soaked plugs = either little to no spark or excessive fuel. in your case, excessive fuel

Just rebuild the carb you hacve or go to a junk yard get a carb and rebuild it
i think the q-jet is a great carb. i think most people who hate them just dont know how to set them up.

hellz yea.rebuilt the carb.got gas spraying everywhere(didnt adjust floats right...facepalm) rebuilt and adjusted the floats the right way to specs and runs great(except for a miss which is a wire on too loose.)it ended up being the needle and seat was corroded to death but i finally got it fixed.first time i rebuilt a carb as well.so +1 for me=)

Ding Ding Ding!!!! i vote the floats arent working and its unlikely but posible the float for your secondaries has gotten a hole in it and isnt floating

you said you lost power to the coil that says electrical and not fuel !! check all the wires
on your starter solenoid and check your ignition switch wires , fusible links on the solenoid !!

no now it runs.the needle and seat were bad originally so i replaced both and then i didnt get the floats set right so i pulled it back apart.i ran a different wire to power the coil on key on.but now it works the needles seat was all corroded and such.but as i said before now it works it was just getting WAY to much fuel.
