The exhaust outlet of the silencer can be rotated 
to any desired position in the following manner:

Loosen the locknut and assembly screw.
Set the exhaust outlet at the required posi-
tion by rotating the rear part of the silencer.
Re-tighten the assembly screw, followed by 
the locknut.

Model engines generate considerable heat. 
Do not touch any part of your engine until 
it  has  cooled.  Contact  with  the  muffler 
(silencer), cylinder head or exhaust header 
pipe, in particular, may result in a serious 
burn. Keep your hands and face away from 
exhaust gas or you will suffer a burn.

Reminder!

Note: 
When  tightening  the  locknut,  hold  the 
assembly screw with a screw driver so that 
the assembly screw may not loosen.

Be sure to use a pressurized fuel system by 
connecting the muffler pressure nipple to the 
vent-pipe of the fuel tank.

FUEL TANK & LINES

Make  sure  that  the  tank  is  well  rinsed  out 
with methanol or glow fuel before installation 
and  that  the  pickup  weight  is  well  clear  of 
the bottom of the tank when held vertically.

For  plumbing,  use  heavy  duty  silicone  tube 
of 2mm inner dia and 5mm outer dia.

The  suggested  fuel  tank  size  is  220cc.  This 
will  give  approximately  13-14  minutes 
running  time  when  some  part-throttle 
operation is included. 

Locate the fuel tank so that the center line of 
the  tank  is  approx.  10mm  below  the  center 
line of the needle-valve.

Approx. 15mm

Locate the fuel tank as close to the
engine as possible to minimize fuel
