5. On VForce3 reeds, inspect the leading edges of each
reed petal. If the edges are chipped, or excessively
worn, replace the reed petals. Inspect the rubber
sections of the inner cage. If the rubber is missing or
damaged, complete reed replacement is required.
REED PETAL REPLACEMENT INSPECTION
If the engine becomes hard to start, idle RPM is higher
than normal, throttle response deteriorates, or a lean
operating condition is encountered, the throttle body
adapter and reed valve assemblies should be inspected.
Inspect each reed petal. There should be no cracks or
chipping on any of the petals.
Inspect the reed cages for damage. Make sure the
rubber tips are not frayed or cracked.
Hold each reed cage up to a light source and verify very
little to no light can be seen around the petal sealing
edges.
