    the other day i go to start the truck and warm it up, after about 5 minutes it dies, Doesnt restart. i figure the plugs have loaded up cuz of the rings letting oil in the cylinders, (when you floor the throttle black smokes comes out like crazy) anyway, i change the plugs and some of them are actually so gummed up there is no gap left. i start the rig up again and it runs for awhile then dies, and doesnt restart, i cannot see gas going in the carb then i press the throttle, It is an Edelbrock carb, i dunno the CFM or anything, What could be wrong? (sorry this is kinda vague)

    check the float or the needle and seat, try cleanin the carb and see if that helps, sounds like its runnin real ritch to me if its blowin alotta black soot, it could be sticky floats or a dirty needle and seat thats causin it to flood itself out /forums/images/graemlins/thumb.gif

    I'll second that. Sounds like a choke issue to me too. Is it electric, mechanical, or do you have it hooked up to a cable. If it is electric, start it, run it just for a minute and then pull the wires off the choke. It'll stumble a little bit, but you should be able to keep it going until it warms up by being easy on the throttle. If that doesn't work then you may have other issues like bad fuel pump and sticky butterfly valves...
