BALANCING CARBURETORS
CAUTION:
Once removing the carburetor side cover from
the carburetor top, it is necessary to balance
the four carburetors.
The four carburetors must be balanced after dis-
assembling the engine or the carburetors. As the
first step, calibrate the carburetor balancer gauge,
as follows:
09913 - 13121
Carburetor balancer
09915- 94511 Adapter
• Start up the engine and run it in idling condition
for warming up.
• Stop the warm-up engine. Remove vacuum
inspection screw
CD
for No. 1 or No. 3 carbure-
tor and install adapter® with gasket.
• Connect one of the four rubber hoses of the
balancer gauge to this adapter, and start up the
engine, and keep it running at 1 750 r/min by
turning throttle stop screw.
• Turn the air screw@ of the gauge so that the
vacuum acting on the tube of that hose will
bring the steel ball @in the tube to the center
line@.
• After making sure that the steel ball stays steady
at the center line, disconnect the hose from the
adapter and connect the next hose to the
adapter. Turn air screw to bring the other steel
ball to the center line.
