THE FUEL SYSTEM AND GOVERNOR

Disassembly and rebuilding the carburetor
1. Clamp-off the fuel line to prevent fuel spillage,
then disconnect the fuel line from the carburetor.
NOTE: If the carburetor is equipped with a
primer, disconnect the primer hose.
2. Remove the carburetor by following the steps
described in Chapter 3: Air Intake and Filter.
NOTE: An insulator separates the carburetor
from the cylinder head.
• A bowl vent port is in a recessed passage
on the end of the carburetor that faces the
insulator.
• A second passage in the insulator supple-
ments the passage on the carburetor.
• Gaskets separate the insulator from the
cylinder head and the carburetor from the
insulator.
• A port in the carburetor to insulator gasket
ties the bowl vent passages together.

3. Remove the bowl bolt using a 10mm wrench.
See Figure 4.15.
NOTE: From this point an assessment can be
made about the viability of rebuilding the carbu
-
retor.
• If extensive corrosion is evident, replace the car-
buretor.
• If varnish build-up is too extensive to clean,
replace the carburetor.
4. When inverted, the float should rest in a level
position.
