Dave,


The point is: Do you think the throttle at 1/2 - 3/4 open is a part of the 'idle range'?

...I can just imagine that model of yours, with the Tower .75 and a Master Airscrew 11x8, adjusted to "idle" at 3/4 throttle, coming in for a landing...


I believe even you agree that the taper of the low-speed needle, in conjunction with the spray-bar/fuel nozzle of the Webra TNII carburettor, does control the mixture strength up to that point.

Yet the manual calls this 'the idle range'... Maybe the translation to English was wrong, but the fact is it can be misinterpreted and the method, by which the tapered tip of the so-called 'idle needle', in conjunction with the 'fuel supply opening in the sparybar', influences the 'idle range' is not explained to the least... even though it is supposed to make you 'grasp the principle'...


You see, Dave? I don't care if half the world calls this second needle in two-needle carburettors the 'idle needle'.

It is much more than that and deserves to be recognized as such.


'Idle range'? there is no such thing.
