bucking!!
My 77 1/2 F250 4x4 400 NP435 bucks now and then and it then hard to start. I can be driving down the road in 3rd or 4th and keeping it steady gas and then all the sudden it starts bucking. To stop the bucking i have to push in the clutch, it i try to give it any gas while bucking it doesn't seem to take the gas it does nothing. A lot of the time it stalls while bucking. Is it the clutch, the carb or both or what? Any help would be great.
Thanks
Jeff

Jeff, first check the filter that is screwed into carb inlet. If that is clear, I think it is either the fuel pump going bad, or vapor lock.
