    Go in the middle of the range is what i shoot for. Same when setting float hts. What did the plugs look like to each corresponding carb?? Fuel to air ratio affects it too. Too rich and it needs to warm up a LOT to get sufficient heat in the cylinders to vaporize fuel easier. Picture putting water in a frying pan cold and it takes a while to boil. Heat the pan up real good and put water in and it instantly sizzles.. Same principle applies with the cylinders.
    General forum wisdom says set the side air screws at 1 1/2 from seated as starting point.

    NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.


    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.
