    • Use a Phillips screwdriver to adjust the carburetor idle screw until the tachometer reads as close to 3100 RPM as possible:

    • Turn the idle screw clockwise to increase RPM

    • Turn the idle screw counterclockwise to decrease RPM

    • Once the idle has been set, shut off the motor and disconnect the tachometer.

Conclusion

The procedure is complete, no further action is required.
