Not sure this is the right place, but I have a 63 F100 with inline 6 262. I recently installed new coil, new points, new spark plugs, new wires, dist. rotor and cap, as well as vacuum advance. It has a single barrel Holley carb. It will run just fine in the garage and I can rev the engine OK. It hesitates slightly during acceleration. I set the timing at 10 deg as that seems to run good.

The problem happens when I drive about 1 mile and then all of the sudden, POP, sputter, POP sputter, and massive loss of running power. It will idle OK, but if I try to rev the engine it just about dies. I was able to limp it home. When I got home, and idling, I checked the voltages (14V at the battery when idling, and 10.2 V at the ignition coil). I am thinking it's fuel as the original tank is in the truck. I replaced the rubber sections, but not the hard lines. Maybe it's getting fuel starved? Any other ideas?

Thanks,
David.

 

How rusted is the tank itself? If there's rust inside the tank, and driving around stirs it up, it could plug the fuel sender, until it sits idle long enough that it all settles back down. Just a thought, anyway. Second thing to look at is the timing advance.

 

From what I can tell the bottom of the tank looks ok, but brownish. I installed a new fuel filter maybe I will pull it and see if there's crud. The timing advance is hard lined to the carb. I just replaced the vacuum advance unit and checked it. It holds a vacuum at the connection to the carb.

I just realized that when I set the timing, the vacuum line was still attached. Should I pull it off when setting timing?

 

timing is set with the vac removed, yes.

 

OK, I'll have to double check. Thanks for the responses.
