Usually timing just loosen your distributer ,the thing wth all your spark plug wires going to it and turn slightly and keep testing your truck until you get it where you want it. after each slight move of half inch or so tighten it back up and fire the truck up to see if it dies.the distributer has a shaft on it and you will see like a half inch bolt to loosen on the intake manifold so yo can turn it
If you have a normal 2bbl carb on there, there are two screws on the front of the bottom plate of the carb. (likely they are exposed if the carb has ever been serviced, otherwise you will need to remove the carb and drill and pry out the covers) Best way to adjust is to set the throttle linkage adjustment screw so that you have the lowest possible idle without stalling and then put a hand held tach and vaqcuum gauge on the engine (you can use one or the other but both are better) turn each screw till you find a point where you have the highest rpms and highest vacuum. Once set, do it one more time but in very small increments. Then, turn linkage screw till you can get an idle rpm of at least 750 to 800 rpm. Providing you have no vacuum leaks and the carb is not dumping fuel, you should be fine. Mas ignition timing with todays poor quality fuel is about 6 degrees Btdc (advanced) Manual will likely list it at 0.
(just in case you want to mess with timing.) No timing light? Advance timing till when you put the engine against the brake in drive, (powerbraking) the engine just starts to detonate, then turn back about 1/4".Then lock the distributer back down.
