MB stopped using carburetors in about 1978 -- the last one was on a 280 six (four barrel Solex) or 230 (sidedraft Stromburg). All gasline engines since are fuel injected.

What looks like a carburetor is the fuel distributor -- it has a plate in a venturi (hole) inside the air filter housing that looks kinda like a choke plate.
