Naa...vapor lock is when you fill the combustion chamber with liquid fuel that cannot be compressed. Here in the US anyway

The opposite of that might be called a flame-out. Generally, that's a too lean condition caused my too much heat and/or pre-burning.

*Please explain hydro-lock, vapor-lock, and flame-out? I assumed the terms were interchangeable because of the "locked" condition...he's just plain ole' not starting.
