I use this procedure on everything - solid or hydro. EOIC works, you don't need a chart or a firing order, just go one cylinder at a time. This is specifically directed at the questions I used to get about setting hydros but I use the same on solids and get it done.

Pick a cylinder.

Bump the motor until the Exhaust valve starts up. Intake is now on base circle.

Loosen the intake lock nut.

WAIT a minute or so, to let the plunger relax.

Twirl intake pushrod between thumb and forefinger (hold gently) and tighten the lock nut until you feel the pushrod stop turning. A little practice is all it takes. You will know - it stops right away, unless you are turning it with pliers. This is zero lash.

Tighten locknut 1/2~3/4 turn.

Bump the motor until the Intake is almost down. Exhaust is now on base circle.

Loosen the exhaust lock nut.

WAIT a minute or so, to let the plunger relax.

Twirl exhaust pushrod between thumb and forefinger (hold gently) , etc...

Tighten locknut 1/2~3/4 turn.

Repeat as necessary.
