This is a replacement carburetor for the following O.S. engines:
O.S. .61 VR-M O.S. .65 VR-M O.S. .81 VR-M O.S. .65 VR-DF
O.S. .91 VR-DF (both the small and large head versions)
One Entire assembled carburetor (Needle valve assembly, carb body, throttle
arm, carb barrel etc.) and instructions for operation.
Two M3.5x10 socket head screws for mounting to the engine.
One Large O-ring seal - This seals the gap between the carb and engine so
no air leaks.
One Aluminum arm for inflight needle adjustment - This is an arm that
installs onto the High-Speed needle valve (when the ratchet spring is
removed) this can then be connected to an extra servo (on a extra
PROPORTIONAL channel) for in-flight needle adjustments.
