My RV-3B had been sitting since last September. Finally put the prop on 
today. Two apex seals stuck. Got them loose by painting with ATF and 
poking with a plastic rod through spark plug hole.

I then tried the cup of water trick. May have removed some carbon, but 
seems there still are some deposits on the rotors.

Runs fine, but ...

Lynn, what is "a warm engine"?

I don't think my oil and water temps got much higher than 170F.
