Reply to "Carb Mixture Screw Tuning"

Bobby are you running a single 44idf or duel?

either way you should have an idle screw per corroborator barrel. I personally like to set the idle as recommended by the the Bob Book. Then back out an additional 1/4 turn. this will help with idle stability at different operating temps. if you keep it at Lean best/fast idle it will change significantly based on the weather and running temp of the engine.

you should be able to hear the RPMs, one key thing to remember is tun a little then wait for the engine to stabilize.. 5-10 sec then turn some more. go slow .... letting the adjustments impacts take effect before turning more. do this for each throat. then start over. you will find that after a couple of cycles you have it nailed down..
