Normally the correct setting of the mixture screws, after engine run-in, is the following:
L (close the screw completely and then open): 1 T.O. (1 turn )
H (close the screw completely and then open): 1 T.O. e ¾ (1 turn and 45’)
Based on various factors as altitude, ambient temperature etc. It might be
necessary to reset the carburettor to optimize the performance of the engine.
ATTENTION:
- Never lean too much as lean mixture will overheat engine and cause seizure.
- Do not force H or L closed. It may damage the precision machined orifice and render the
carb. unserviceable.
- The adjustment of screw must be performed with warm engine.
