Two things we do in the starting regiment:
1) allow two minutes to pass from when you finish priming the cylinders before starting. This allows the fuel to vaporize in the cylinders.
2) immediately prior to starting, prime the main pipe (primer to the left) the pump the throttle full fwd and aft twice prior to setting it at the 1/3 point.
Holding the starter on after you hear firing, does help and does not damage the starter as it would an electric starter.
We use a rule for priming, 1 pump for every 10 degrees C below 100.

Russian manual recommends 2-3 minutes in summer between priming & starting, rising to 3-4 minutes in winter due to lower fuel vapourisation rate.
They also warn about over-priming as this "washes" oil off the cylinder walls & presents a hydraulic lock risk too ... it only needs an eggcup of liquid.
If you've a manifold drain, leave it open during priming & you will be surprised as to how much fuel can pour out even with 6 or 7 cylinder primes.
