Remove the carburetor from the engine before
disassembling. Clean the outside of the carburetor
thoroughly with solvent. Do not use compressed air to
dry at this time.
2.
Remove all top cap screws (1), top cap (2) and gasket
(3).
3.
Locate the arm screw (4) and loosen it just enough to
move the arm (5) out of the way so that you can
remove the needle (6) e-clip and the plastic washer
from the throttle slide.
NOTE: Keep track of the plastic washer (9), and place
it so it is on the top of the throttle valve when installing
the needle and e-ring back into the carburetor.
4.
Inspect the needle (7), e-clip (8), and plastic washer
(9) for wear.
5.
Remove the four screws (10) on the funnel face.
6.
Turn throttle shaft so the throttle slide (11) slides open
all the way.

With slide fully open, pull funnel (12) out from the
bottom first. Inspect the gasket (13).
8.
Check for wear on the faces of the slides.
