Disassembly and rebuilding the carburetor
1.
Clamp off the fuel line to prevent fuel spillage and 
remove it.
2.
Remove the carburetor by following the steps 
described in Chapter 3: Air Intake and Filter.
NOTE: There is a corresponding passage recessed 
into the mating surface where the throttle end of the 
carburetor housing meets the gasket. See Figure 
4.43.  
3.
Remove the bowl bolt using a 10mm wrench. See 
Figure 4.44.
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.
4.
When inverted, the float should rest in a level posi-
tion. See Figure 4.45.
5.
Remove the pin that the float hinges on to remove 
the float.
