14.4.7 Adjusting Screws
Grommet has been removed for the
sake of clarity.
There are three adjusting screws on
the carburetor:
H = high speed screw (1)
L = low speed screw (2)
LA = idle speed screw (3)
If the carburetor cannot be adjusted
properly, the problem may be the
adjusting screws.
The high speed screw H has a
limiter cap, which has to be
removed before the screw is
removed.
Always install a new limiter cap.
– Remove the carburetor and pull
off the grommet,
