A diagnostic tachometer should be used for
this procedure. Results may vary depending
on whether testing is conducted with the
flushing attachment, in a test tank, or with the
outboard motor in the water.
1.
Start the engine and allow it to warm up
fully in neutral until it is running smoothly.
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty veri-
fying the idle speed, or the idle speed requires
adjustment,consult a Shunfeng dealer or other
qualified mechanic.
2. Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 23.
