Found mine
Little red devil in front of rear oil cooler, oriented vertically
arrow down, into airframe (and I assume back to manifold and tanks)
Same?

Pulled, cleaned,
did a light sun n blow test.
Seemed OK
Re-installed.
No change.

That said, it relies on its internal spring to stay UP and closed, and spring is very weak.
So IN airplane might still drool?
So maybe replace anyway?
Later models they mount horizontally. Probably for that reason.

QAA.com says with mixture in idle cutoff,
light pressure in the flow divider and its check valve shouldn't really matter.
cutoff is cutoff.

Other ideas?
