I am lookig at a 1960 Ford F100 with Big Block 460, 750cfm Carter Carb
and a 410 ford 9inch rear end. The owner says it idles poor when the
fuel level is low. Can anyone guess what the real problem of the rough
idle is?

Weak fuel pump

Could be a lot of things, improper idle mixture, vacuum leak, stuck
float causing over rich mixture, burnt valves, bad headgasket, bad
plugs just to name a few. There is no one cause of this.

It idles rough when the fuel level is low. Any guesses?
_________________________________________

If the only variable is fuel level, then the pumping system needs
the added pressure from a higher fuel level to assist pumping.

A new fuel pump and a new fuel line filter/carb inlet filter may help.

Good luck.
