I did a fast search on the thing, and it appears that the floatless carburetors were available on german engines since WWI. But they entered russia in the hands of an italian airships builder, Nobile. After Hitler's arrival, and the german military industry withdraw from russia, the soviets managed to develope a native version from the old german one.

Maybe on the M82, the history is different, but is surprising that something so old was not taken by the allies at the end of WWI.
