QuestionI have a 1981 Ford F100 300 L6, hasn't ran since about mid-2000. This past weekend replaced the following with new or remanufactured parts: ignition control box, distributor cap and rotor, spark plugs and spark plug wires, fuel pump and fuel filter(installed a clear inline between the tank and pump), carburetor (1 barrel), all rubber fuel lines (3 of them), water pump and water outlet housing, thermostat (195 degree Failsafe), upper and lower radiator hoses, both heater hoses, both alternator belts and power steering belt, alternator and voltage regulator, starter, solenoid and battery. Dropped the fuel tank, cleaned out, put fresh fuel in. Fresh oil and filter.
Put the new remanufactured carb on, runs for about 15 seconds then dies. Only vacuum lines on are the distributor, transmission and PVC, Other carb outlets capped. Most emissions is off.
Why isn’t it staying running?
Answernext time you start it spray a fine mist of carb cleaner in carb and see if it will stay running sounds like either rich or lean if lean it should run with a little mist of carb spray and if it does look for vacuum leak especially around intake to head area-try adjusting carb
if it don't make sure butterfly on top of carb is opening slightly when it starts if not crack it by hand and see if it helps. followup.
