1. Please note the best mixture strength around half opened throttle is obtained with the balanced controls of both Needle valve and Mixture Metering Screw E SETTING BEFORE ENGINE STARTING Close turn clockwise the Needle Valve until it stops Open the Needle Valve 3 turns from the closed position Make sure that the throttle linkage is set so that the throttle rotor is fully open when the transmitter stick is move to full high speed position and that the throttle rotor is fully closed when both the throttle stick and throttle trim lever are moved to the lowest position m ADJUSTMENT Following procedures are recommended to adjust the carburetor Adjustment low speed performance range from idle to 1 3 opened throttle 1 Start the engine with transmitter throttle stick fully down and the throttle trim level set the neutral position 2 Set the throttle trim lever so that the engine runs with highest idling rpm but without engaging the clutch 3 Increase the engine speed by advancing the transmitter throttle stick gradually until the helicopter just lift up floats from the ground Warm up the engine by keeping above floating condition for approximately 10 seconds then slowly reduce the engine speed land and allow the engine to idle for a while 4 Repeat above procedure several times If the engine tends to hesitate or stop after hesitation the mixture at idle is not correct Generally speaking if the mixture at idle is too r

3. Since the carburetor has been pre set at the factory large adjustments of this carburetor should not be required However under different operating conditions minor re adjustments may be required These conditions include set up of the helicopter glow plug used and weather conditions E IMPORTANT Before trying to adjust the carburetor please note the following issues In helicopters engine failure in flight as a serious problem especially for the inexperienced modeler It can mean loss of control and resulting crash For ensuring safe and reliable control on the helicopter flight it is a must that the engine keeps running and that the throttle has quick and reliable response Therefore the carburetor adjustment is very important for the helicopter and this should be done with great care to obtain an optimum throttle response In the helicopter flight the throttle response on the medium speed range with the partial throttle opening is very important Because medium speed range is widely used in the flight On this carburetor only two adjustable controls are provided 1 Needle Valve This valve controls the mixture strength of the engine speed range from half to fully opened throttle 2 Mixture Metering Screw This screw controls the mixture strength of the speed range from idling to half opened throttle Basically the adjustment of this Mixture Metering Screw is to obtain the steady idling and smooth acceleration response
