Question:
    hello, i have an TTPRO-39H(R) Helicopter Engine on a raptor 30v2 but it has a problem with the carbirateur. I solve it but i have lost the settings for Mixture Metering Screw , and the manual doesn't say something for the default setting of this screw. What can I do to set it correct? Thanks a lot Harris Goulimis
Answer:
    Dear Harris, Thanks for your email. When the throttle is fully open, close (turn clockwise) the Mixture Metering Screw until it stops. Then open the screw 5.5 to 6 turns from the closed position. Please note that the screw can not be turned to tight that may occur damage. Please also feel free to contact Ruberkon Ltd. in Greece as the following for technical support. Ruberkon Ltd.
