The Mercury 1139-1135 Carburetor, specifically the KB10A model, is a classic piece of marine outboard engineering that was in production between 1975 and 1979. This carburetor is designed for engines with power outputs ranging from 2.4 to 4.5 horsepower, making it an ideal choice for smaller boats or personal watercraft.

It features a simple throttle and idle adjustment system, allowing you to fine-tune the engine's performance to suit your specific needs. The carburetor also has a float bowl drain, which makes it easy to clean and maintain, ensuring optimal performance over time.

In summary, the Mercury 1139-1135 KB10A carburetor is a reliable and durable piece of marine outboard engineering. Its efficient air and fuel mixing, manual choke, and easy adjustment system make it a popular choice for boat owners looking for a reliable and high-performing carburetor.
