It's right there in the Bentley manual.
In the case of a not-pumped up lifter that's in the engine, I adjust the
rocker until the lifter is just making contact, or a tiny bit more. .  After
I run it some, I adjust more.  You can tell a good lifter from a not pumped
up one easily when adjusting them.  
  I've seen them have to run several hours before all the lifters are pumped
up.

Subject: sigh..... lifter adjustments?

81 air cooled. The engine is apart, and has been sitting around for a
month since it was last run. Lots and lots of miles on the existing
valve train components.

I am reading all the info on adjusting the lifters, but so far,
everything refers to a warm engine, or one that was run "last night" to
pump up the lifters.

What is the recommended procedure/number of turns from zero lash when
starting from scratch with a stone cold motor, and likely more than on
or two lifters that have leaked down?

Thanks,

John
