Make sens to me, your method is similar to what others have described to me. By performing the the two steps described at the beginning of this sequence, I will know that the fuel already arrived to the ignition chamber and most important the right or near the optimal amount of fuel to allow the engine to start.

This is what I do to start with my ZDZ 50:

Choke On, Ignition off, full throttle.
Flip prop, paying attention to the noise of the engine/exhaust, hard to describe in words when it changes, then I know that the fuel is in the ignition chamber (takes around 15 flips), at this point stop flipping.
Ignition on, high idle
it fires at right after one flip.

I used pretty much the same method with my BME 44, which by the way was hard to start.

That afternoon I tried to apply this approach, since I am not used to the engine/exhaust noises, the only way for me to tell that I already have fuel at the engine was by looking at fuel line at the carburetor end. Harder to apply when the cowl has been already installed.

I will try that next time.

Thanks again.
