Adjusting Idle Mixture Screws Does Nothin - Quadrajet
after rebuilding my Rochester Quadrajet 4MV I wanted to adjust the idle mixture screws, YouTube says to adjust by RPM or vacuum, well nothing happens when I screw the screws in or out, no change in RPM speed
what could it be? it could be a poorly adjusted choke it could be a vacuum leak anything in particular I should check and how 1974 GMC 1/2 ton manual 350 V8 all stock |
