This is a C100 Intake Manifold, a critical component of the engine's intake system. It is suitable for Mopeds, Cub series, and ATVs, and fits engines including 139FMB, 147FMD, 147FMF, 150FMG, and similar models.

The intake manifold connects the carburetor to the cylinder head intake port, delivering the air-fuel mixture from the carburetor into the cylinder. Manufactured from quality materials with excellent sealing properties and oil resistance, it is an ideal replacement when the original intake manifold is aged, cracked, or damaged.

This C100 intake manifold fits the following engine models:

• Mopeds - Various 50cc-150cc moped models
• Cub Series - Honda Cub and clone models
• ATVs - Small-engine quad bikes / kids ATVs
• Mini Moto / Pocket Bikes
• Other vehicles using 139FMB, 147FMD, 147FMF, 150FMG engines

The intake manifold is a critical component of the engine's intake system, directly affecting engine performance:

• Air-Fuel Delivery: Transports the air-fuel mixture from the carburetor to the cylinder – essential for engine operation.
• Sealing Function: Ensures the intake passage is sealed, preventing air leaks that cause lean mixture conditions.
• Idle Quality: Intake manifold leaks can cause rough idle, high idle, or hard starting.
• Performance Critical: The condition of the intake manifold directly affects intake efficiency and engine power output.

• Rough Idle: Engine vibrates at idle, RPM fluctuates, stalls easily.
• Poor Acceleration: Sluggish throttle response, feels underpowered.
• Hard Starting: Difficult to start cold or hot, requires multiple attempts.
• Backfiring: Intake backfire or exhaust popping.
• Increased Fuel Consumption: Air leaks cause lean or rich mixture, increasing fuel usage.
• Hissing Sound: Audible hissing noise from intake area at idle.
• Deteriorated Gasket: Rubber gasket hardened, cracked, or lost sealing ability.

If you experience these symptoms, inspect the intake manifold and gasket, and replace if necessary.

• OEM Specifications: Manufactured to original specifications for perfect fitment.
• Quality Materials: Made from oil-resistant, heat-resistant materials for long service life.
• Precision Machined: Precise interface dimensions ensure proper fit with carburetor and cylinder head.
• Reliable Sealing: Smooth mounting surface works with gasket for excellent sealing.
• Direct Replacement: Perfect substitute for aged or damaged original intake manifolds.
• Wide Compatibility: Fits 139FMB, 147FMD, 147FMF, 150FMG and compatible engines.

1. When replacing the intake manifold, it is recommended to replace the gasket at the same time to ensure proper sealing.
2. Clean the cylinder head intake port and carburetor mounting surfaces to remove oil and debris.
3. Install the gasket with the correct orientation.
4. Tighten mounting bolts in a cross pattern to avoid warping.
5. Check that the carburetor is securely mounted with no looseness after installation.
6. Start the engine and check for air leaks and stable idle operation.
