No such on the MK-1 PCFs. I don't know about MK-3s. Never crewed on one.

Agreed re: runaways. I was told a story about a LARGE marine
engine where the teller's farther was the hero; everyone else
fled and he rammed a bale of cotton waste into the air intake,
stopping the engine. It too had an air cutoff door, but the
runaway just ate it & kept going.
I ran into this with a VW Rabbit a friend owned. Not good.
Burning SAE 10W-40 vs #2 melts the glowplugs as well as not
stopping when you need it to.
I like the CO2 idea; just be sure it's not a dry power
extinguisher when you grab it.

If dry powder is all you got, it will probably work in a pinch and would be
better than letting the engine blow apart. I wouldn't want to predict what
damage the powder would do to the engine though.
In preparing to extinguish a small engine room fire caused by a welder I once
had a Chief MM snatch a dry powder extinguisher out of my hands before I could
trigger it. He quickly replaced it with a CO2 unit which made a lot less mess
than the dry powder would have.

That powder is VERY corrosive inside a running engine... Most insurance
appraisers will declare the engine SCRAP, if it was stopped with a Dry
Chemical Extinguisher, or require it to be IN-Framed before they would
insure it on a Machinery Policy, again.... Just say'en....
