You lost me somewhere on the road, you said

MODEL RSA-5 AND RSA-10AD1
<snip>
A. Cold Starts
1. Mixture control in the idle cut-off position.
2. Set throttle 1/8 open.
3. Master switch - ON.
4. Boost pump switch - ON.
5. Move mixture control to FULL RICH until the fuel flow indicator reads 4 to 6 GPH then immediately return
mixture control to cut-off position.
Classic priming for cold start, boost pump ON + mixture full rich for a couple of secs. Ok so far.
B. Warm Starts
Use the same procedure for cold starts except the boost pump may be left "off" and step 5 eliminated.
DO NOT PRIME
This is the "skip priming" procedure, because boost pump is off, and mixture is not temporally set to rich, well known from the AFM.
But you were recommending something different:
When "hot" there is no need really to prime. Fuel pump "ON" for 5 secs - do NOT set mixture to "RICH" - fuel pump OFF. Hit the starter and when it starts slide mixture to RICH.
That'll be "boost pump pumping against the closed (idle cutoff) mixture valve".
I definitely never came across this one.
So was that a typo and you meant the standard don't prime regime or
is that a special, born out of experience, procedure?
