Need to know how to adjust a carburetor for a 1977 half ton ford

in the 70s it has 2 screws on the front bottom of the carb for idle rich .

an the one on the side for the gaspedal idle spring return,

then there was the timing too on the distributor.

an one more....vacuum advance.

best to keep your vacuum up an working well with no leaks .

it sets the points timing by moving the distributor angle. replace it with a electronic points would be nice.

then there\'s that gook on your float in the carb. if it sticks you\'ll use up the gas an it will stutter or fail in gas reserve.

getting the correct gaskets would be the issue now for a carb overhaul. check that gas filter . an if you\'v never drained your tank its likely got water or rust.

Well the engine is fuel injected, so no carb is used.
Base idle is set at the factory, and the computer adjusts idle speed depending on load by controlling the amount of air entering the throttle body thru the idle air control valve.

Sounds like the accelerator pump circuit in the carb is not squirting fuel in when you depress the accelerator. That is why you get the lag in acceleration before it decides to launch. When you open the carb you should get a steady stream of fuel from the accelerator pump. With the engine not running look down the carb throat and open the throttle blades and visually check to see that there is a stream of fuel when doing so. If not time to rebuild the carb, or just get another accelerator pump for
the carb.

I have a cross flow 1300 gt with a weber carb that is us would a nikki carb do the job of the webber carb.

havent woorked on one of these in years ,used to build them on the assembly line in the 70s ,yes a nikki carb would do fine providing you get the right one ,these vehicles used a non progressive carb ,ie - the first venturi opened then the second one ,also all these engines from the first ones in 1971 have stelite coated valves and valve seats so you can use unleaded fuel of 98 octane in them.The tappet settings were done in the factory with a vacumn gauge and they do suffer from wear under the tappet face but the tappet is heat treated so dont reface them on a grinder ,replace them .tappet settings were if i remember for a gt were 12/14 inlet and 18/21 exhaust but i alway done them to 12 and 16 any tighter and it will drink petrol ,also the timing advance was different it advance a lot more compared to the normal engine,got me going now as i cannot remember the distributor code or the paint code on the thermostat housing on the head ,i do remember they had yellow build cards with GT in teh top right hand corner and heavier flywheels with bigger clutches .thanks for the memory jerker it makes a change from monster american cars on here and auto boxes ,Also built V6 zodiac engines as well as V4 transits

Connecting vaccum

I don't remember factory specs but most chevy v8's like about 8 to 12 degrees advance (BTC) Depending upon the fuel quality, you may need to pull back on that a bit. Vacuum hose is also optional as to position. I like using a carb port that is above the throttle plate so advance comes in later. If the engine "lays down" on acceleration, move the hose to any port on the baseplate or manifold that has full vacuum at idle. These are not factory settings but are the ones I used as routine when setting up those engines, when emissions equipment and inspections were not at issue. (but even so, most always passed inspection anyhow.)

Have a qualified mechanic rebuild your original carburator and reinstall it with all the original vaccum hoses and controls functioning properly.

Someone smarter than you and I, designed this engine to function properly with the feedback carburator. Installing an aftermarket carb negates the entire emision control system and will not allow the engine to "Breathe" properly.
