On my ax I like to start it with a reverse snap of the spinner against the compression stroke
with the engine primed rotate counter clockwise grab the spinner with your thumb & first two fingers
give a firm snap clockwise the prop will bounce off the backside of the stroke most times it will fire on the first snap.

Give it a try no risk to your fingers & no stress on rod/wrist pin/crank from an electric starter (hydro lock)
never flip a prop bare finger.
