- After fuel fills the hole of the delivery valve holder for the No. 1 cylinder, rotate the flywheel in the clockwise direction 90 degrees.
- Rotate the flywheel in the counterclockwise direction to 10 degrees before top center.
- Continue to rotate the flywheel slowly in the counterclockwise direction. Stop rotating the flywheel when fuel begins to come up in order to get injection timing.
- Check the degree mark on the flywheel. The flywheel has an identification mark for the crank angle before the top center of the No. 1 piston.
