OPTION 2: ENGINE MOUNT, FUEL TANK

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 
surface of the tank. It should not touch the top of the 
tank.

To carburetor
fuel inlet

(see front view of fuel tank). Insert and tighten the screw.

Be sure to equip
 air vent pipe.

Tubing for
re-fuelling

Not included.

Tygon tubing (Gas). And
silicone tubing (Methanol).

5mm

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.
