I got my hot little hands on a brand new (not factory rebuilt) Q-Jet #1902. My question is what should I do to it before installing it on the engine? This is my first carb. I assume that it will run just fine as is after proper tuning, but I want this carb to function more reliably off road. Is there some kind of off-road modification(s) I should make to the q-jet before I install it? I don't need really radical performance out of it, I just don't want it to quit on me when I'm on a steep incline, and I want the power to be there for me when I need it. Fuel efficiency is an issue to, I don't want to see the gas guage move down every time I romp the pedal. This is going on top of a '74 K5 with a 350 engine. Pretty much everything is stock.
