Re: got the q jet on finally
The mixture screws are on the front of the carb, inside the base plate. If that is a late 70's, early 80's carb, there's a good chance that the screws are sealed from the factory. The books I have on the carb give recommendations on how to cut into the base plate and safely knock out the plug that keeps you from reaching the screws. But hopefully this isn't the case. There are two screws, for each primary venturi.
I live and die by the Qjet on my rig. Just threw on a shop rebuilt one a few hours ago. I abused mine till it took no more. They're awesome offroad. Good luck.
