Finally, a (working) see-through carburettor.

"TALK" can change everything.   The "BLIP" switches weren't used for long. IF you had an exhaust manifold you'd blow it apart cutting the ignition. and putting it ON again ' The depicted carb is over simplified.  ' The  throttle butterfly turns the airflow on and off as you push the throttle forward and back again.   The venturi provides the "suction" to pull fuel through from the bowl  and provide a mixture/ A choke of that type is used for flooding it for starting. It does much the same thing as putting your hand partially  over the opening . Fully closing it will stop all air from passing  and draw a lot of neat fuel in.. A venturi makes more fuel flow as the airflow increases but will become increasingly richer as more air flows due to the differing natures of the 2 fluids.  and you must correct for this aspect of it by generally introducing an air bleed of the right size into the fuel  flowing into the venturi  to compensate.  They have also a separate mini system for the idle situation where there is not enough airflow through the venturi at small throttle openings to suck fuel through the main jet...

Generally nothing to do with aviation, but that “Smarter every day” channel is worth watching (and they seem to manage to get at least one explosion in most episodes 😛).

It was mainly on the rotary engines (Gnome Monosoupape), they had no variable throttle valve, only minimal control on the valves and cutting the ignition either all or some cylinders. This resulted in the typical engine noise of engine off - engine on when coming in to land (same while starting up/idling/taxiing).

If you thought these engines were simple, watch this:

The "Single" valve "monosoupape" is only one version and what it does is draw some air in after the exhaust has exited and then add rich mixture from the crankcase  You can see the little holes drilled inthe lower part of each cylinder. It's not been made very clear inthe presentation.  It's pretty low volumetric efficiency.. This avoids the short life spring loaded valves in the pistons of the earlier Gnome et Rhone which would backfire into the crankcase if one failed as all the mixture there was of the correct ratio to burn.. Later the name was changed to Le Rhone about 1915. The lube oil was Castor oil and quite a lot of it as well which went out through the exhaust.. You can pick those engines by the curved inlet pipes from the crankcase to  the top of each cylinder. Nev
