    Truck is tough to crank but when it does start, it idles well... press accelerator and it bogs down...If i slowly depress pedal it revs fine at high rpm. Has new plugs. thanks for any tips!!!

    do the simple stuff first
    compression test.
    check the dist cap /rotor button
    check wires
    fuel filter

    accelerator pump on the carb isn't working....remove the intake hose and with the engine off and the choke plate open so you can see into the carb...floor the throttle rapidly..you should see a jet of fuel from the accelerator pump if it's working
