Valve adjustment

[Jim Davis <jamdav@woodward.com>]

Listers,
This has probably been beaten to death before, but do you adjust the valves
when the engine is hot or cold?  I have seen it stated both ways in various
manuals.

Another question I have regards the carburetor temp compensators, is there a
quick on engine check that can be performed?  None of the publications I
have read even begin to touch on the subject.

And yes, I am chasing some sort of engine sputtering demon that occurs at
~3000rpm.
  
Thanks,
