What are the valves?

Attached to the admission of two-stroke engines, the valves are flexible strips opening on the gas intake from the carburetor. They then return to their place, to prevent the return of fresh gas. And more torque and power at low and medium engine speeds is obtained if the seal valve and carburetor gasket are tight.
