WARNING
Compressed air can pierce the skin and flying debris
from compressed air could cause serious eye injury.
Wear safety glasses when working with compressed air.
Never use your hand to check for air leaks or to deter-
mine air flow rates. (00061a)
Clean all internal air/fuel passages in carburetor housing with
carburetor cleaner. Blow out passages using low pressure
compressed air. Proceed as follows:
Slow Speed Circuit
1.
See
Spray carburetor cleaner into air inlet
hole of slow speed circuit. While spraying, verify that
solution exits slow jet bore at bottom of carburetor hous-
ing. Placing finger over slow jet bore, verify that solution
exits four pin holes just inboard of the throttle plate, as
well as the single pin hole outboard of the throttle plate.
2.
Using a tapered, rubber-tipped nozzle on the air hose (to
prevent both loss of air pressure and to avoid scratching
or nicking the bore), apply low pressure compressed air
into air inlet hole to blow carburetor cleaner out of slow
jet bore. Placing gloved finger over slow jet bore, blow
carburetor cleaner out of pin holes inboard and outboard
of throttle plate.
Main Circuit
1.
See
Plugging main jet hole in carburetor
throat, spray carburetor cleaner into air inlet hole of main
circuit. While spraying, verify that solution exits main jet
bore at bottom of carburetor housing.
2.
Using a tapered, rubber-tipped nozzle on the air hose (to
prevent both loss of air pressure and to avoid scratching
or nicking the bore), apply low pressure compressed air
into air inlet hole to blow carburetor cleaner out of hole in
carburetor throat. Placing gloved finger over hole in car-
buretor throat, blow carburetor cleaner out of main jet
bore at bottom of carburetor housing.
Float Bowl Vent
1.
See
Spray carburetor cleaner into air inlet
hole of float bowl vent. While spraying, verify that solution
exits two holes in float bowl chamber at bottom of carbu-
retor housing.
2.
Using a tapered, rubber-tipped nozzle on the air hose (to
prevent both loss of air pressure and to avoid scratching
or nicking the bore), apply low pressure compressed air
into air inlet hole of float bowl vent to blow carburetor
cleaner out of holes in float bowl chamber.
