FUEL SYSTEM
INTAKE MANIFOLD
Inspect the intake manifold:
•
All gasket surfaces must be smooth and free of
nicks.
•
Use a machinist's straightedge to check for flat-
ness in all directions. The gasket surface must
be flat, ± 0.003 in. (0.08 mm).
Disassembly
IMPORTANT:
Do not disassemble leaf plate
assemblies unless leaf plate seats, leaf valves, or
leaf stops are damaged or corroded.
Remove two screws per leaf valve and remove
the leaf valves as required.
When disassembling leaf plate assemblies, do not
lift or bend leaf valves. Remove the leaf stop
screws and remove the stops, shims, and leaf
valves.
When disassembled, keep the stops, shims, and
leaf valves separated by assembly.
IMPORTANT:
The 9.9 and 15 leaf valves are
not interchangeable. The thickness of the valves
is not the same.
Assembly
IMPORTANT:
All intake manifold components
must be perfectly clean before assembly. Do not
use a strong carburetor cleaner or hot soaking
tank.
Place leaf valves on leaf plate. If new valves do
not seat on the leaf plate, turn the leaf valves over.
IMPORTANT:
Used leaf valves must not be
turned over for reuse. Leaf valve may break when
returned to service, causing serious powerhead
damage.
If any leaf valves are standing open, apply light
pressure using a pencil eraser. If leaf valve closes
with light pressure, valve is acceptable. If not,
inspect leaf plate for high spots or burrs.
IMPORTANT:
Do not lap leaf plate. If plate is too
smooth, the leaf valves may stick closed after off-
season storage.
Apply Locquic Primer to mounting screws and
allow to air dry.
