    My 1991 350 magnum runs well but needs a tweek on the mixture screw as it does not run as smooth as it could. It does not misfire though. Is there a special tool for adjusting the carb as I can see the adjusters but getting to them seems impossible. Is it a flexible shaft adjuster?

    "Here is a link to sears where you can buy the correct tool.

    It is also the one I have, it comes with 5 tip ends for different configurations.

    I am assuming it is a rochester 4bbl.

    I just slip a 1/4" drive socket over the screw which gives me something to grab w/my fingers. I have a 2 BBL Mercarb w/1 screw behind the T'stat hsg.
    Fix minor things (replace wear items for preventative maintenance.) that cause major problems before they break.

    "The Rochetser 4BBL has two unique a/f screws that are difficult to get to, to say the least.

    Most especially the older motors it was near impossible to reach with my tool never mind a 1/4 drive socket.
