Hi Ron ! Idle circuits work from low rpms up to about 3000rpm , so most of your driving /cruising is done on them. The mains overlap slightly with the idles. They operate somewhere between 2500rpm upwards. Its not exact with these ranges as you would expect. The important factor is constant rpm testing. If you drive it and maintain a constant 2500 rpm you are listening/feeling the idle circuit at work. If you are holding it in gear at 3500 then you are on your mains. Its good to have the window down and a lonely street !! Play with different combos. Its the only way you can really jet it.
Good Luck ! David
