(A) ADJUSTING THE IDLING
● After engine startup, set the idling at about 2000rpm, turn the L needle to the right (to
reduce fuel), and search for the position for the max. engine speed. From that position, turn
the L needle about 1/4 (90°) to the left (to increase fuel), set the idling speed with the idle
screw or the transmitter.
(B) ADJUSTING NUMBER OF ROTATIONS AT FULL THROTTLE
● Achieve full throttle slowly.
When the engine speed stabilizes, turn the H needle to the left and right to locate the
position for the max. engine speed.
● From the position of the max. engine speed, open the H needle 1/8 (to increase fuel) to make the setting.
In general, consider 100rpm to be the difference between the max. engine speed and the set engine speed.
● After making the setting, return to idling. Accelerate rapidly and confirm that there are no problems with acceleration. If
acceleration is poor, open the L needle an additional 1/8th (45°) and confirm that acceleration is smooth. In this case, the
idling will be low, so use the idle screw or transmitter to adjust it.
● This engine has had the carburetor set at the standard position at time of factory manufacture. Thus, no calibration is
normally necessary.
In keeping, if poor acceleration or insufficient speed at full throttle or the like result, make adjustments in conformance
with the main points of adjustment after engine startup.
However, the idling will change depending on the size of the propeller used, which will make adjustment using the idle
screw or transmitter necessary.
