Half right ... once an engine fires the manifold vacuum and exhaust pressure extinguish any carby or stack fires.

The main, well documented, issue on WWII war-birds was the glow of the hot manifolds at night, interfering with pilot visibility (especially in high mounted manifold designs like the hurricane and spitfire) and making the aircraft a target to night fighters. A number of different design features were tried to mask this manifold glow.
