4. Slowly move the feed-pump-knob up and down to
pump fuel.
The operating load on the feed-pump-knob is light
when air is pumped inside the fuel pipe, and so on,
but it becomes heavy when fuel is pumped.
Refer to the number of operations in the following
table to operate the feed-pump-knob.
Work description

starter continuously for 10 seconds, turn if off for 30
seconds. And then repeat this a couple of times.
8. When the engine is started, wait for approx. 1
minute without performing any operation.
Afterwards, race the engine to purge a small
amount of air remaining in the fuel system.
9. In spite of the preceding step, if the engine stall
occurs due to air remaining in the system, perform
air purging again.
