looped and also longer than the other
ones.

4.Start the engine and let it run at
idle. 5.Check that ignition timing is at the
standard value. Standard value: approximately
10° BTDC
note |
- The ignition timing may fluctuate within
±7°. This is
normal.
- In higher altitude, the ignition timing
is more advanced than the standard value
by approximately 5°.
- Wait till approximately 1 minute passes
after the engine started, and check the
ignition timing when the engine
stabilized.

6.Run the engine at 2,500 r/min for 2
minutes. 7.Set the CO, HC
tester. 8.Check the CO contents and the HC
contents at idle. Standard
value
CO contents: 0.3 % or
less HC contents: 200 ppm or
less
9.If there is a deviation
from the standard value, inspect the MPI system (Refer to
GROUP 13B - Troubleshooting - Inspection chart
for trouble symptom ). 10.Remove
the HC, CO tester and timing light. 11.Turn the
