This range of engines is ideally suited to a variety
of R/C aircraft, including trainer, sports, aerobatic
and scale types.
A separate precision-made needle-valve unit is
installed at the rear, where manual adjustment is
safely remote from the rotating propeller.
INTRODUCTION
With these engines, the piston will feel tight at the
top of its stroke when the engine is cold. This is
normal. The piston and cylinder are designed to
achieve a perfect running clearance when they
reach their intended running temperature.
Note :

•
Carefully insert plug, with
washer, fingertight only, before
final tightening with the correct
size plug wrench.
BEFORE INSTALLING THE ENGINE
Installing the glowplug
Connect the short length of fuel tubing (supplied)
securely between the needle-valve outlet and
carburetor inlet as shown in the illustration on the
next page.
In the event of the tubing becoming damaged, it
should be replaced with a suitable length (as
indicated below) of best quality 5mm ODx2mm ID
silicone tubing. Use similar material to connect the
fuel inlet nipple to the fuel tank.
