clear them of filth with compressed air. Blow
each fuel passage of carburetor clean with
compressed air. And install them in their

vertically to the float chamber and in
alignment with the main jet. The standard
fuel level is 18.5mm. After inspection, fit the

Generally, fuel level adjusting screw has already
been adjusted before leaving factory. There is no
need for adjusting. If need be, it should be done by
a professional.

Run the engine 3-5 minutes. Adjust the idle screw
with a screw driver to keep the revolution within the
range of 1700±170rpm. The adjusting screw
should usually be screwed in gently and screw out
by 2 3/8-3 7/8 turns.
