So cover the carb with thumb, turn prop until you just see fuel entering the carb, insert glow ignitor then tightly grasp propeller and push through compression stroke, and start flipping with stick once there is no 'bump'.

Do you stop priming when you just see fuel enter the carb, just before, or a spin or two after?

I can't say I love the idea of gripping the prop with the engine full of fuel and the glow ignitor in place.
