O.S. Engines 46LA-S - Manual (Page 8)

INTRODUCTION
The "LA-S Series" engines are designed for control line
models. They have broad power characteristics which
are suitable for both trainer models and stunt models.
A separate needle-valve is mounted at the rear, where
manual adjustment is safely away from the rotating
propeller.
The 'midnight blue' external finish may be
decolorized by very high surface temperature or
by certain solvents. Such decolorization does not
affect engine perfor-mance, however.

Connect the short length of fuel tubing supplied
securely between the fuel outlet and the fuel inlet. In
the event of the tube becoming damaged, it should be
replaced with a suitable length of best quality 5mm
ODX2mm ID silicone tubing. Use similar material to
connect the fuel inlet nipple to the fuel tank.
