Instruction Manual
7
Locate the long piece of wire used for the throttle
pushrod. One end of the wire has been pre-bend in to a
“Z” bend at the factory. This “Z” bend should be inserted
into the throttle arm of the engine when the engine is
fitted onto the engine mount. Fit the engine to the engine
mount using the screws provided.
OPTION 2: ENGINE MOUNT
1. INSTALLING THE STOPPER ASSEMBLY
1)
The stopper has been pre-assembled at the
factory.
2)
Using a modeling knife, cut one length of silicon
fuel line (the length of silicon fuel line is calculated by
how the weighted clunk should rest about 8mm away
from the rear of the tank and move freely inside the
tank). Connect one end of the line to the weighted
clunk and the other end to the nylon pick up tube in
the stopper.
3)
Carefully bend the second nylon tube up at a 45
degree angle (using a cigarette lighter). This tube will
be the vent tube to the muffler.
4)
Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This tube will
be vent tube to the fueling valve.
When the stopper assembly is installed in the tank, the
top of the vent tube should rest just below the top sur-
face of the tank. It should not touch the top of the tank.

5)
Test fit the stopper assembly into the tank. It may
be necessary to remove some of the flashing around
the tank opening using a modeling knife. If flashing is
present, make sure none of it falls into the tank.
6)
When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine screw until
the rubber stopper expands and seals the tank opening.
Do not over tighten the assembly as this could cause
the tank to split.
7)
Using a modeling knife, cut 3 lengths of fuel line
150mm long. Connect 2 lines to the 2 vent tubes and 1
line to the fuel pickup tube in the stopper.
