Question about the compression test, what will that show? Not that I doubt you at all, I just wondering why it would work great warmed up but not cold?

Usually when compression is low, isn't it hard to start in the mornings? I can start my car without glowing the plugs, right away even when cold in the morning, of course I do glow the plugs, just saying that it will start right away even without letting the plugs glow.
