5. Re-synchronize carburetors following carburetor
installation. Refer to “Timing/Synchronizing/
Adjusting” Section 2C.
6. Attach bleed hose to back of air box.
7. Secure air box to carburetors with bolts.
IMPORTANT: Inspect all fuel hose connections,
and carburetor float bowl split lines for fuel leaks
with outboard running. Also inspect each carbu-
retor throat, with outboard running at low RPM,
for fuel dribbling out of vent tube which would be
indicative of a float and/or needle and seat as-
sembly not functioning properly.
IMPORTANT: Outboard should not be operated
above 3000 RPM with air box cover removed as
outboard will run too lean and internal damage
could result.
8. Reinstall outboard cowling.

MAINTENANCE
Periodically check fuel line and primer bulb for
cracks, breaks, restrictions or chafing. Check all fuel
line connections for tightness. All fuel line connec-
tions must be clamped securely.
Primer bulb assembly has 2 check valves: Fuel inlet
(toward tank) and a fuel outlet (toward engine).
The fuel inlet valve allows fuel to fill primer bulb but
closes to prevent fuel from returning to tank when
bulb is squeezed. The fuel outlet valve opens when
primer bulb is squeezed to allow fuel flow to carbure-
tor, but closes as bulb is released to prevent fuel from
returning to primer bulb.
