302 HO rough running

I have an 84 F150 4x4 with a 302 HO. The engine runs very rough at any speed and sometimes will not start. When it won't start, the front four spark plugs are dry, while the back four are wet. It has a new coil and distributor cap. Is this a problem with the carb or ignition? Thanks

Its leaning more toward the carboration end of the spectrum. Sounds like the Carb is messed up. Or your having a vacumm problem on the intake side.
