This item for control accelerator cable to the Mechanical Buffalo.
Dimension - 4.3" x 1.8"
Weight  -  150 gm
 
Lever Accelerator Cable: A throttle cable connected to a hand lever to control the engine’s throttle, likely for a carburetor (e.g., PZ19 or PZ22) on a small engine. The cable actuates the throttle valve to regulate engine speed, engaging the centrifugal clutch.
Mechanical Buffalo: Likely a ride-on toy, mini bike, or small agricultural machine with a gasoline engine and a hand-operated throttle lever. The term is not standard, but “buffalo” could refer to a brand, model, or colloquial name for a rugged, compact vehicle.
Dimensions (4.3" x 1.8"): These likely describe the throttle lever assembly or the cable housing’s compact mounting area (e.g., lever size or cable bracket dimensions). Alternatively, they could refer to the throttle control unit’s footprint. The exact interpretation is unclear without a diagram.
Weight (150 gm / 0.33 lbs): Indicates a lightweight cable assembly, typical for small engines in go-karts, mini bikes, or toys, with a short cable length and minimal hardware.
Context from Clutch: The twin belt clutch (3.5" x 4.8" x 3.3", 4 kg) suggests a compact centrifugal clutch for a 3/4" or 20mm short shaft, likely for a 6.5–13 HP engine. The cable must be compatible with the engine’s carburetor and throttle lever setup.
 
Analysis of Specifications
Dimensions (4.3" x 1.8"):
Likely refers to the throttle lever assembly (e.g., a thumb or hand lever’s mounting plate or housing) rather than the cable itself, which is typically measured by length (e.g., 61"–100").
Alternatively, it could describe a compact throttle control unit (lever + cable housing) or the carburetor linkage area.
For comparison, a thumb throttle assembly (e.g., 1PZ 22T-C28 for ATVs) has a handlebar mount ~4–5" long and ~1–2" wide, aligning with your dimensions.
 
Weight (150 gm):
Very lightweight, suggesting a short cable (e.g., 24"–36") with minimal hardware (e.g., plastic lever, thin steel wire, lightweight housing).
Typical go-kart/ATV throttle cables weigh 100–300 grams, depending on length and materials (e.g., stainless steel vs. plastic).
 
Mechanical Buffalo Application:
Likely a small, low-powered vehicle (e.g., 50cc–250cc engine) with a hand-operated throttle, similar to go-karts, ATVs, or ride-on toys.
The cable connects a hand lever (possibly thumb-operated) to the carburetor, controlling engine RPM to engage the twin belt clutch.
 
Compatibility:
Must fit a small engine carburetor (e.g., PZ19 for 50cc–125cc, PZ22 for 150cc–250cc) with ~1" throttle travel.
Common end fittings: eyelet or barrel for the lever, bare wire or Z-bend for the carburetor.
