How the heck do you adjust a Q-jet?!? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Working on my sisters 69 3/4 GMC, and it seems to be running a little rich. I was gonna adjust it, but I can't find the screws. I noticed two holes on the front at the base of the carb that appeared to have little tiny bolts inside. Is that where you adjust it? Do you need some special tool to do it? How much does this carb flow, it will need to be replaced soon as it appears to be leaking fuel from the secondary shaft onto the manifold. I don't want to over/under carb it. It's the stock 350 4-bolt, the Q-jet looks original too.
