and seat assembly operation to be tested. Operate
throttle lever several times and observe discharge from
pump jets before installing carburetor.

CARBURETOR OVERHAUL
The following procedures apply to a complete over
haul with the carburetor removed from the engine.
A complete disassembly is not necessary for per
forming routine service adjustments. In most instances,
service adjustments of the individual circuits can be
performed without removing the carburetor from the
engine. Refer to Service Adjustment Procedures.
A complete carburetor overhaul includes disassembly,
thorough cleaning, inspection and replacement of the
gaskets and worn or damaged parts. It also includes idle
speed and mixture adjustment (if necessary) and fast
idle adjustment after the carburetor is installed.
NOTE: When using an overhaul kit, use all parts in
cluded in the kit.
