For this kind of engines to start on a boardstarter without any messing with the ignition, need two things: instant acceleration, and a high enough RPM to get the engine passing TDC against ignition on its own inertia.

If you want to start it with a lower RPPM, you need retardation to close to TDC, if you want to start it with a slow accelerating starter, you need to temporary cut ignition until "firing speed" is reached.

Which of the options you choose is up to you.
Judging that video based on my own experience with starting problems on a Zenoah G230, I would say that your current starting RPM is on the low side, and acceleration is way too slow. Fix those problems, and it will most likely start reliably and instantly.

Brgds, Bert
