Remove the carburetor retaining screws and remove the
silicone tube between the carburetor and cover plate.
Then, pull out the carburetor gently from the intake
manifold.
Rotate the carburetor 180 and insert on the intake
manifold straight and gently. Do not force at an angle or
the O ring inside the carburetor may be damaged.
Re-install the retaining screws. Then, connect the
carburetor and cover plate with a new silicone tube of

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 2.5mm inner
dia and 5mm outer dia.
The suggested fuel tank size is 500cc or 14 oz. This will
give approximately 10 minutes running time when some
part-throttle operation is included.
Locate the fuel tank so that the center line of the tank is 10
to 15mm below the center line of the needle-valve.

Locate the fuel tank as close to the engine as possible
to minimize fuel level variation.
