The carburetor body consists of two cast parts. The upper half contains the float chamber cover, float hinges, fuel inlet and outlet fittings, fuel fine filter, spring-loaded needle valve, dual air intake, air dampers and part of the vacuum-controlled economizer valve.
In the lower half of the body is placed a float chamber, an accelerator pump, two diffusers with sprayers, throttle valves, levers, jets and an economizer valve.
Throttle valves are arranged in such a way that the primary opens first, and then the secondary follows, so that both valves are fully open at the same time.
The diffuser of the first chamber, throttle and atomizer are smaller than the secondary ones, while the dimensions of the diffuser of the first and second chambers are the same.
All mixture systems are located in the lower half of the carburetor body, and the main metering systems operate in both chambers, while the idle and economizer valve systems operate only in the primary chamber, and the mixture enrichment system in the secondary chamber.
The accelerator pump sprays fuel into the diffuser.
A fitting is installed on the lower half of the housing to control the vacuum ignition timing controller.
The carburetor has a fully automated choke type choke for easy cold starting.
