I recently went up 2 sizes on my main jet, but I haven't fattened up the air/fuel mixture because I wasn't sure which way to turn it. On a cv carb, if I'm not mistaken, it's a pilot screw, which is an air screw, so I need to turn it clockwise to richen it, right? Someone correct me if I am wrong. Thanks.

 

If it is an Air screw and is located (upstream) of the throttle valve then you
are correct to turn it clockwise to richen!
