Designed with a 1\" (25.4 mm) bore and a 1\/4\" (6.35 mm) flat keyway, it fits a wide range of single‑cylinder and small multi‑cylinder gasoline engines. The unit is compatible with 2B belt profiles and is sold as a single clutch assembly (OEM part number 200630); professional fitting is recommended to ensure alignment and longevity.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this clutch engage and at what engine speed?\u003c\/h3\u003e\n\u003cp\u003eThe clutch uses centrifugal activation: moving weights inside the housing push outward as engine RPM rises, transferring torque to the belt only after a target speed. Engagement occurs in the range of roughly 2,000 to 3,600 RPM, which gives a predictable take‑off for go karts, ATVs and small utility vehicles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEngagement range: ~2000–3600 RPM\u003c\/li\u003e\n  \u003cli\u003eDesigned for gradual, automatic connection—no manual shifting\u003c\/li\u003e\n  \u003cli\u003eSimplifies starts and protects engine from stall during load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat engines and machines is this compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis clutch fits engines rated between 8 and 16 horsepower that accept a 1\" bore with a 1\/4\" flat key.
