You need to start with a base adjustment first.
making sure the fast idle cam is disengaged, turn the idle speed screw all the way out so it is not touching the throttle stop.
Now turn it in till it just touches the stop plate and add 1 1/2 turns in.
Bottom the idle mixture screws (Lightly so not to score them) and turn them both out 1 1/2 turns.
Check the choke settings, move throttle linkage to set choke.
look to see where the fast idle screw is resting on the fast idle cam behind the choke coil housing and how much it has opened the throttle blades.
adjust the fast idle screw to open or close the throttle plates to correct rpm setting. 1200 works well.
Start eng and check float settings, should just barely seep fuel out the hole whiile running.
Bring eng to operating temp and check that choke has opened and released fast idle cam.
adjust idle speed screw to 700 rpm.
Now your idle mixture screws should make noticable changes when moved in or out.
Now I use an old trick to balance both sides of the mixture.
I move the choke plate to allow the fast idle cam to raise the idle to approx 1000 rpm. then tweek the mixture screws to give the smoothest idle by turning each slightly and listening for changes. a little will turn will do a lot.
Now you can adjust the axcell pump. I start with the pump screw gapped at .005 clearence to the pump. and adjust tighter or looser to time the squirt so there is no flatspot or bog when you hit the throttle.
