DISASSEMBLY
1. 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. The float chamber could become pressurized
resulting in damage to the floats or inlet needle and seat.
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 (G), 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.
7. 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,.
CAUTION
