Steve,

You may just be lucky or your fuel systems tolerate the unlocked
primer better than others.  A good friend of mine, who has over
1000 hours of flight time and has built five airplanes, had trouble
with my Tripacer primer on two occasions .  It was not fully closed
and locked and caused a fuel leak on the ground after shutdown
and very rough engine while taxiing in.  I suspect it was compensated
for in flight by leaning the mixture which he did on a regular basis.
I suspect it was closed at startup but not locked and opened a bit
during flight.

As for priming during cranking, since my cowl fire I'm all for priming
with the engine turning over if you can manage with the setup you
have.  I now use my accelerator pump on the throttle to prime with
the engine cranking.  Not all carbs have the accelerator pump so
that may not be an option for everyone.

Someone mentioned they were surprised at all the post generated
by the primer issue.  You never know what pushes someone's hot
button.  I attended a meeting once with our entire service team where
we had many business issues to cover.  The item that pushed
everyone's hot button was washing the company vehicles.  My
manager left the meeting shaking his head in disbelief.
