This type of gasket, fits and can be used on many 2cycle engines, between the carburetor and manifold. The small pulse hole has to be lined up with the pulse hole on the manifold, or make a path from the carburetor's pulse hole to the manifold's pulse hole. As to allow the engine's crankcase pulses (pressure and vacuum)to be delivered to the carburetor.
A leaky carburetor, manifold gasket will causes the user, many difficulties. Like stalling engine, not starting, rough running, won't idle.
