I can't believe this is any good for your engine!  When you crank it
without ignition, any gas vapor which is sucked into the cylinders will
wash the oil off the cylinder walls.  Gas is a poor lubricant compared
to oil.  I believe you will increase the wear by following this practice.

It is also quite bad to "punch" the gas when shutting off an engine.
I know a lot of people who do this, apparently to prevent run-on.  They
are in effect trying to flood out the engine.  The problem is that once
again, raw gas is being dumped into the cylinders.  It washes down and
dilutes the oil - NOT GOOD!

An engine in good running condition should not need to be primed before
starting.  If you need to do this, there is something wrong.  Old
quadrajet carbs were notorious for this causing this kind of problem.
The secondary jets are just pressed in.  Eventually they leak, causing
the fuel in the bowl to drain into the engine.  Then, when you try to
start the car, there is no gas in the carb.  People "fix" this by adding
a sealer (like epoxy!!) around the jets.
