Well after a little more inpspection of the carb, I am getting a healthy stream of fuel from the acc pump. When the truck is running the fuel level is right in the middle of the sight glass. When I bump the throttle I do get a loud woshing sound from a little gismo mounted in the aircleaner housing. Not sure if that was there before or not. I am going to check the plug wires next, but it sure seems like a carb problem to me. ANy more ideas guys, Thanks Stinson
