SUZUKI CARBURETOR 13200-91J70 REC13200-91J70

Function and technical context

The carburetor is the component responsible for mixing fuel with air in the proper proportion to ensure efficient combustion in small displacement petrol outboard engines. In Suzuki DF4, DF5 and DF6 engines, this element works within the fuel supply system, regulating the mixture flow according to the load and engine speed conditions. A carburetor in poor condition directly compromises the engine's response, causes irregular fuel consumption and can prevent starting or cause acceleration failures while sailing. This carburetor has Suzuki references 13200-91J70, 13200-91J81 and 13200-91JB1, as well as Johnson Evinrude references 5036191, 5036192, 5036549 and 5037520, and is suitable for DF4, DF5 and DF6 series models manufactured between 2002 and 2011.

When to replace this part?

The most common symptoms of a damaged carburetor include difficulty starting when cold, unstable idling or jerking during acceleration, stalling of the engine at full load, and presence of unburned fuel residue in the exhaust. In engines that remain unused for long periods, the jets and internal passages tend to become clogged due to the degradation of petrol, which makes it advisable to check or replace the carburetor at each seasonal tune-up. Replacing the carburetor preventively at the first symptoms prevents major breakdowns in the fuel system and guarantees optimal performance throughout the entire nautical campaign.
