Walt, you are terribly mistaken. Self-priming and
positive displacement are NOT one and the same. I
have been bending wrenches professionally for over 30
years now and priming an engine is a GOOD thing.
Remember, until the pump does it's thing none of the
rotating parts will have oil flow. No oil, damaged
parts, period. Even a self-priming pump will have a
lag time. Your choice then, a couple of minutes of
preventive effort or internal damage (maybe minor,
maybe not).
And yes, I have to admit laziness in this area also,
but with knowledge of the particular engine and also
the consequences.
If a pump won't stay primed, that is a totally
different matter.
Dave
