F6A carburetor idle mixture screw for engine start-up

This video shows how important the idle mixture screw on the F6A suzuki carburetor for the engine start-up. As requested of one of my subscriber, I'm doing the adjustment without the use of tachometer and vacuum gauge, just listening skills and observation to the engine behavior to set the idle mixture screw for the engine to start. But for precise setting, I suggest to use the tachometer (for idle base screw rpm setting) and vacuum gauge (for idle mixture screw vacuum setting). most cases of rich mixture settings happen on the incorrect idle base screw adjustment.
