It goes something like this:-
Chock in.
Lift left hand cowling.
Depress small button on top of carburetor float chamber until fuel runs out of the drain. This fills the float chamber.
Close cowling.
Check that the pilot has the switches OFF. They can be seen as they are on the outside of the fuselage.

Pull prop through four compressions.
It goes something like this:-
Chocks in.
Fuel on.
Lift RH cowling and press small button on top of carburetor float chamber until fuel runs out of drain. This fills the float chamber. Close and latch cowling.
Yell at pilot, "Throttle shut, Switches Off. Sucking In."
Check that the switches really are OFF by looking at them. They are on the outside of the left fuselage. Normaly a set for the front and another for the rear. The one set may be ON but the others must be OFF.
Pull prop through four compressions to draw fuel mixture into cylinders.
Yell at pilot,"Throttle set, Contact. He should advance the throttle about 1/2 to 1inch and put the switches Up for ON.
Pull prop through and it should start.
If it does not start in a reasonable number of pulls you now need to Blow it Out. This is to clear the cylinders of a too rich mixture.
Yell at pilot. Switches OFF, Throttle OPEN.
Rotate the prop backwards for anything up to a dozen compressions.
Yell at pilot, "Throttle shut, switches OFF, and confirm as before.
I always pull it through one compression at this point.
Yell at pilot,"Throttle Set, Contact.
Pull the prop through in the correct direction and it will burst into life, with a bit of luck.
Why do you yell at pilot. 1) He is a pilot!!
2) He is wearing a Biggles helmet and cannot hear too well and your arm or neck is in line for trouble if he gets it wrong.
