1.4 Inspecting and adjusting the fuel
injection timing
(1)
Preparations
(a)
Close the fuel filter cock.
(b)
Disconnect the No. 1 fuel injection pipe at
both ends.
(c)
Remove the No. 1 delivery valve holder. Take
out the delivery valve and the spring. Install
the delivery valve holder only.
(d)
Reconnect the No. 1 fuel injection pipe at the
pump end only to see the fuel flow.
(e)
Set the speed control lever to LOW speed.
(2)
Inspecting the fuel injection timing
(a)
Open the fuel filter cock. If the engine is
equipped with a fuel pump, turn the key ON.
Note: Place a container under an open end of the fuel
injection pipe to collect fuel coming out in the
next step. On the engine equipped with a fuel
pump, be prepared as fuel will come out fiercely.
(b)
Slowly rotate the crankshaft clockwise. Fuel
will come out of the fuel injection pipe. The
injection timing (IT) is just when the fuel stops
coming out.
Note:
When fuel has stopped coming out, slightly
rotate the crankshaft in the reverse direction and
then slowly rotate it clockwise to let fuel come
out. This will show more exactly when fuel stops
coming out.
(c)
Just when fuel stops coming out, the IT mark
on the crankshaft pulley should be aligned
with the counter mark on the gear case.
