The Gipsy Major engine in our Chippy is primed by flooding fuel into the inlet manifold and pulling the prop through 4 compressions.
and when that doesn't work resort to the
FAILSAFE STARTING PROCEDURE
Switches off, throttle
closed.
Tickle fuel pumps.
Suck in 4 blades.
Throttle wide open.
Reverse 16 blades.
Throttle closed.
1 blade forwards.
Now try swinging it with the mags on.
And if that doesn't work get a couple of riggers to hold the tail up so that all the cylinders get an even amount of priming.
If that doesn't work, retire to the bar!
