How do you adjust 6hp Tecumseh snow blower carb?

To adjust the carburetor on a 6hp Tecumseh snow blower, first locate the adjustment screws: the high-speed (H) and low-speed (L) mixture screws. Start the engine and let it warm up, then adjust the L screw for optimal idle performance, turning it clockwise to lean and counterclockwise to enrich. Next, adjust the H screw while the engine is running at full throttle for best performance under load. Always make small adjustments and allow the engine to stabilize before making further changes.
