Carburetor Settings:
    High Speed Needle, 2-2/2 turns clockwise from flush
    Idle Screw: Set throttle trim on transmitter so that throttle is in
neutral position, turn screw counter-clockwise to reduce idle
speed, or clockwise to increase idle speed. Set idle speed high
enough to keep engine running efficiently, however not high enough to
engage the clutch.
    Low Speed Needle: No adjustment recommended. For increased
efficiency, set after high-speed needle is adjusted. Turn needle
in 1/8 turn increments for better bottom end throttle response.
Caution-never turn in more than 2 turns from flush. This will
trigger engine to run too lean and will result in damage.
