Hi Jeff,
I modified my Classic cowling early on, with a starboard NACA inlet on
the lower cowling, and started out with a 2" scat tube
to the plenum chamber. This turned out to be too small for the 912S, and
it became necessary to enlarge the inlet to 3".
It enabled me ,however, with a home-made 3" to 2" Y , to also supply air
to 2 ball vents in the cockpit, as well as making the engine happy.

Hi All,
While I have Gold Rush in for the winter annual I'm considering some
cowl changes. Including closing off the upper NACA use for induction air
on the 912-S and using the lower starboard NACA normally used for the
914 induction. I seem to remember someone else using that for carb
intake and under cowl carb heat. I'm going to use the same air plenum
with the same filter as now but I will fabricate a side intake to attach
to the top of the plenum and a 2 inch scat tube coming up from the below
NACA. My question is this. I already have the inlet plumed for this 2
inch tube and not a lot of room to increase it to 3 inch. My concerns is
if the 2 inch would be enough for both carbs. Has anyone else done this
with the 912-S and if so what size of tube did you use?
Best Regards,
Jeff R.
