Well, you need both for combustion.

... but the fact is that on this airplane (and most fuel injected
engines, I believe) the fuel won't flow into the engine unless the
throttle is open.

You can easily test this by turning on the aux fuel pump and advancing
the mixture to rich while keeping the throttle fully closed. You'll
sit there all day without seeing the fuel flow meter move.


Besieds which - even if you get the engine to start with the throttle
closed, you will need to advance it as soon as it starts, necessitating
a third hand.
