This product is a YP100 Carburetor, part number MIYP100-5081. It is a CVK-type (Constant Vacuum) carburetor specifically designed for 100cc JOG 149QMG 4-stroke scooter, ATV, and dirt bike engines — a core component of the fuel delivery system.

The carburetor is responsible for mixing fuel with air in the precise ratio required for combustion. The CVK design uses a vacuum diaphragm to control the throttle slide, providing smooth throttle response and excellent fuel economy. This carburetor is equipped with an electric choke (auto choke) that enriches the mixture for cold starts and automatically closes as the engine warms up — no manual operation required. This carburetor is the ideal replacement for the original factory unit, restoring starting performance and acceleration response.

• ⛽ CVK Vacuum Diaphragm Design: Uses a vacuum diaphragm to control the throttle slide for smooth throttle response and excellent fuel economy.
• 🔥 Electric Choke (Auto Choke): Automatically enriches the mixture for cold starts and gradually closes as the engine warms up — no manual operation required.
• 🔧 Precise Fuel Delivery: Main jet, pilot jet, and needle are precisely calibrated for accurate air/fuel mixture across all operating conditions.
• 🛡️ Corrosion-Resistant Materials: Carburetor body made from precision die-cast aluminum; internal components use fuel-resistant materials for long-term reliability.
• 🔄 Direct Replacement: Mounting flange, fuel connections, and choke wiring plug match OEM — installs without any modifications.

✅ Typical Signs That Carburetor Replacement Is Needed:
• Cold starting difficulty — requires multiple attempts or manual choke operation.
• Unstable idle — stalling or fluctuating idle speed.
• Poor acceleration — hesitation or sluggish throttle response.
• Abnormally high fuel consumption or black smoke from exhaust.
• Visible clogging, corrosion, or damaged internal components.
Replacing a faulty carburetor promptly restores engine power, improves fuel economy, and reduces emissions.

✅ Installation Tips:
1. Disconnect the battery negative terminal before installation for safety.
2. Remove the old carburetor and clean the intake manifold mounting surface.
3. Install the new carburetor, ensuring the flange seal is intact (replace gasket if necessary).
4. Connect the fuel hose, vacuum hose, and choke wiring connector.
5. Attach the throttle cable and ensure proper free play (approximately 2-3mm).
6. Start the engine, allow it to warm up, then adjust the idle speed to specification (approx. 1500-1700rpm).
Professional installation and tuning by a qualified technician is strongly recommended. Improper carburetor adjustment may cause rich or lean running conditions, affecting engine performance and longevity.
