Note that there is a typo in those Haynes instructions... the 4th line down
under check & adjust should be 'Valve No,* 2*'.



The chart does make the 'Rule of 9' quite apparent.

If you have a hand crank it greatly simplifies the process.

Probably mentioned somewhere but having the plugs out is also helpful.
