P15 Carburetor for the Massimo MM-MB100 Mini Bike

Our P15 carburetor for the Massimo MM-MB100 mini bike is a high-quality go-kart component that is a suitable replacement to the original carburetors that were used on Massimo engines. These 98cc engines were also commonly used on gas-powered electric generators and other small engine applications such as mini bikes.

Because a mini bike's carburetor works best when the air that flows into it is clean, we offer this fine carb with an optional high-performance air filter to keep the dust and crud out, or without any optional filter. Whether you only need the carb or if you prefer one of the carb & filter combinations, we are sure that our easily-installed P15 carburetor will enhance your engine's performance. This carburetor is equipped with a manual choke.

Note: This filter assembly includes a velocity stack. This is the large machined alloy ring with a beveled inside diameter that fits into the rubber base of the filter. When mounting this filter assembly, always make sure that the wider end of the hole is inside of the filter and the smaller or narrower end of the hole is on the carburetor side. When properly mounted, the stack functions as a venturi, smoothing the air flow into the carburetor and likewise smoothing the engine's running.
