Disassembly and rebuilding the carburetor
1. Clamp off the fuel line to prevent fuel spillage and
disconnect it from the carburetor nipple
2. Drain the fuel into an approved container.
3. Remove and discard the fuel line.
4. Remove the carburetor by following the steps
described in Chapter 3: Air Intake and Filter.
5. Remove the bowl screw using a 10mm wrench. See
Figure 4.17.
NOTE: From this point an assessment can be made
about the viability of rebuilding the carbure-
tor.
• If extensive corrosion is evident, replace the
carburetor.
• If varnish build-up is too extensive to clean, replace the carburetor.
6. Remove the rubber bowl gasket. See Figure 4.18.
7. Remove the pin that the float hinges on to remove
the float.
NOTE: The float is not adjustable. The needle valve
is suspended from the float by a wire hanger.
See Figure 4.19.
NOTE: Because the needle valve is crucial to the
functioning of the carburetor, and the viton
tip of the valve is subject to wear, it is sug-
gested that technicians replace the valve
float and hanger any time the carburetor is
disassembled for cleaning.
