Today I went out to fly and performed my usual pre-flight. One item I always do is pull the prop through at least 4 compression strokes while noting the compression on each cylinder. Well today one cylinder felt weak. I won't bore you with the diagnostic details as that isn't the point of this post, but the cylinder head turned out to have a crack between the valve seats. Not uncommon. No flight today and have to order a new cylinder head tomorrow.
Point is that pulling through a complete cycle during preflight is a good idea if you don't already do it.
