Question type: Maintenance & Repair

I have a 78 k10 4x4 with a 350. After it warms up it
has a hesitation when you rev it up. Is it possible to
adjust the carb without a vacuum gauge?

Could be the accelerator pump inside the carb, take the air cleaner assembly off so you can see down the air horn and move the throttle by hand and watch for a good steady stream of fuel out o the discharge ports, you should see two separate streams and they should start with even the slightest throttle movement. so if they are not steady and last the full stroke of the actuator rod the pump diaphragm needs replaced. However if and when you tske the top off the carb and see a bunch of crud floating in the bottom of the bowl you better just overhaul it and check the bushings in the throttle plate, if there is too much movement it will be impossible to set it properly after the overhaul. this old things are bound to wear out.
