balancer alignment mark approaches the notch in the engine front cover tab.
If a valve moves as the alignment mark moves into position, the engine is
in the number 6 firing position. If this happens, turn the crankshaft
clockwise one revolution in order to reach the number 1 cylinder firing
position.
- With the engine in the number 1
firing position, adjust the exhaust valves for cylinders number 1, 3, 4, and
8 and the intake valves for cylinders number 1, 2, 5, and 7.
