Kawasaki FA210 Carburetor Adjustment

Idling adjustment of the slow channel mixture (air-fuel ratio) when the engine is idling. If this adjustment is incorrect it can cause irregular starting, erratic idling, engine stoppages and increased fuel consumption. To obtain an initial setting, first screw the pilot airscrew right in, then unscrew it by the specified amount. The soft pilot airscrew taper-section is easily damaged, so make sure it is only lightly screwed in, not tightly. Pulse pump model: Pilot air screw initial setting - Unscrew 1-1/4 turns. Float model: Pilot air screw initial setting - Unscrew 1-1/2 turns.

Next, unscrew the idling limiter to the point where it does not reduce engine speed any more, then place the speed control lever at the lower end. Start the engine and let it warm up thoroughly. Float model: For this screw the fuel cock home, then unscrew it 1-1/2 turns to turn the fuel supply on. Gradually unscrew the throttle stop screw until the engine speed drops almost to the point of stopping. Then turn the pilot air screw to bring the engine speed up just a fraction; the engine speed will come up gradually and then suddenly drop.

Determine the point where the engine speed is highest, and leave the pilot air screw at that setting for the moment. Gradually unscrew the throttle stop screw to reduce the engine speed until it is barely turning over. Screw the pilot air screw either way to see if doing this raises the engine speed at all. When turning the pilot air screw either way no longer increases, the engine speed, carburetor adjustment is finished. The pilot air screw opening at this point is its final setting, and will be within ±1/4 turns out from the initial setting.
