Start with your pilot air screws out 1 1/2 turns from lightly seated. To lean the idle out turn the screw counter clockwise. As far as your idle screws adjust them to allow your sled to idle at about 1800 RPM. Make sure the carbs are close to identicle in this setting.

Pilot air screws are located to the rear of the idle adjust screw. They are small slotted screws. They only effect the idle to 1/4 throttle circuit. If this is not your sleds problem then don't adjust them.

how much do you think it would cost me to bring it down to the shop to have them set the carbs?
