Saving Old Seagulls

Been reviewing the posts here about compression. Did I read that it is unimportant that as long as the Gull runs, it' OK and not worth worrying about? Within reason of course? Cad someone enlighten me please?

Crankcase compression or combustion chamber compression?
What engine are you running?
40-century-102?
All will vary a bit. Some better than others. Some will start easier as a result from better compression, then again some won't.

Compression DOES matter.
