Nicely done...! That takes me back a few years (more than I care to remember) with our old DC-6B in and around West and Central Africa. Never stand too near when stirring up the dust on these dirt strips...!
P&W dual 9-cylinder engines, pretty robust and we had few problems although they did not like going out of hot and high strips with a heavy payload (ours was a DC-6B converted to freighter). Had a timing problem once and err, umm, some idiot set the 'scope timebase in the FE 's position one cylinder bank out and that caused some head scratching until I realised what I had done (oops...now you know who the idiot was).
The carburetor has what they called an "air screen" in the air scoop feeding the carb. The carb was an injection type that metered fuel in ratio to the mass air flow going to the engine (MAF determined by the throttle opening). PS: I'm not an A&E tech (I'm Avionics) so hopefully I've remembered/described it correctly.
Gosh I miss Africa, lived there in the 90's. No TSA mess at that airport Just hop on the plane and go.
Does anyone else remember the "Polk County Pot Plane" back in 1975, where a very skilled aviator put down a DC-4 into a 1,000 foot bulldozed dirt strip at night with a strip of 100 watt bulbs for lights in the mountains... Since the payload was very light stuff he was apparently able to get it stopped in about 500 feet... I recall the news stories about it at the time..pretty amazing feat... Here's a link...

Seemed to be enough runway... wonder why the pilot used reverse thrust? Whenever I've landed on unsealed strips the pilots use the brakes and minimal/no dust gets to the engine intakes (I'm not a pilot... but I've landed on unsealed strips hundreds of times).
