CARBURETOR CLEANING AND INSPEC-
TION
To clean the carburetor, soak all components
thoroughly in a good carburetor cleaner, following
the manufacturer's instructions. Be sure to remove all
carbon from carburetor bore, especially in the area of
the throttle valve. After soaking, clean out all
passages with filtered, compressed air.
Check the adjusting needles and nozzle for damage.
If the float is loaded with fuel or damaged, replace it.
The float should fit freely on its pin without binding.
Check the choke and th rottle shafts for excessive side
play and replace if necessary.
Carburetor repair and gasket kits are available from your nearest
Onan Parts Center.
