Once the fuel tank is installed check for any fuel leaks, and then once there is not any fuel leaks
start the ATV and warm the engine for five to ten minutes. You will still need to adjust the fuel
screw and the idle screw for maxium performance as per the instructions earlier in this section.
The spark plug will let you know if the mixture is running lean or rich by the color on the
tip; the proper color for the tip of the plug is a beer bottle brown. If the engine is running lean the
plug will be a white or light gray in color
do not run the engine with it running lean severe
engine damage may result
, if it is running rich it will be black with carbon and maybe wet
with fuel. It is better to run the mixture on the richer side than the leaner side. A new plug will be
needed each time the spark plug is found in any one of these conditions, and an adjustment is
needed the only way to tell the condition is with a new plug each time, the plug will still be
useable just not for good for this test.
Throttle Cable Adjustment
The next adjustment is to ensure
that the throttle cable is pulling
full throttle and to set free play in
the thumb throttle lever. There is
a turnbuckle assembly located
under the front panel and under
the front of the fuel tank; (see
picture right) although this
picture is taken with the fuel tank
off this adjustment can be made
with only the front panel
removed. The thumb throttle
should have 2-4mm of free play
before it tightens up and starts to
pull the slide up. Then check the
throttle limit screw and make sure it is not limiting full throttle.
NOTE:
If the child is young and
inexperienced loosen the jamb nut and turn the screw all the way in (clock wise) to limit top
speed until they are experienced and can handle the speed and can operate the ATV with total
confidence; then back the screw out to the child's experience can handle the speed. Make sure
once the screw is in the position you want and then tighten the jamb nut while holding the screw
with a screw driver.
