351W Problems

I have a 1985 Bronco! I love it to death and wouldn't trade it for anything. I was riding down the road, came to a stop light and when the light turned green i hit the gas and my 351 started jumping RPM's, the truck idels fine but when its in gear and I try to go down the road it does the same thing. I have tryed the fuel filter (it has a Holley 4180) the carb is brand new. I replaced it with a referbed stock carb. I replaced the fuel pump and thats not it. Adjusted the floats and thats not it. Does anyone else have any ideas??????

Thanks

Sounds like it has a carb iknowitall......

What exactly do you mean by "jumping rpms?" Does it sputter when you accelerate from a stop? Also what tranny do you have?? Manual or Automatic?? Does it do it if you rev it up in neutral or if you gently accelerate? Have you done a quick visual inspection of the cap/rotor, wires and plugs?
