You would think an overly rich mixture would result in smokey exhaust (black) but not from that little beauty of a radial engine. it must be in top shape.
awww man that akes me back to my child hood ...grew up around crop dusters my father Flew them for years he now flys an otter for a jump club....but i can remeber mixing chemicals .....early mornings.....and having to cycle that bloody prop threw so many times in the morning pre flight lol but yeah i have seen the flame .....it is kinda kewl to watch it on a late evening take off
I think close relatives of these planes work as fire bombers in Western Australia. Coincidentally the same shade of yellow, they are used almost like a crop duster to "bomb" bushfires
When flying at dawn, dusk or night depending on the engine settings you can see flames out of the exhaust that are maybe 3 feet long. Usually when cruise flying the mixture setting will reduce the amount of unburnt fuel that can generate the flames.
Radial engines use carburetors and when operated in full rich mixture there's an excess of unburnt fuel that ignites on the exhaust pipes. That's the cause.
No, not unusual for aircraft piston engines, both radial and inline. Night operations in WWII were difficult because the blue exhaust flame could blind the pilot and were easy to spot by enemy forces. Different exhausts and covers were used by all forces to control exhaust temperature and flame for night flying.

its running rich. The extra fuel burns in the manifolds. At low RPMs many engines are run rich to help cool the engine.

Yeah i realise this, but it's not usually blue (hotter), or that constant, correct?

Constant blue exhaust flames is a bit unusual isn't it? What caused that?
