CARBURETOR FOR CHAINSAW 5200S (VEH25106)
The Replacement Carburetor for 5200 Series (52cc) Chainsaws is an aluminum-alloy fuel management component engineered specifically for 2-stroke outdoor power equipment. Widely utilized as a direct replacement part across multiple brands of 45cc, 52cc, and 58cc chainsaws (such as models 4500, 5200, and 5800), this carburetor precisely regulates the engine's air-to-fuel ratio to maintain consistent power delivery, clean throttle acceleration, and seamless idling.
Technical Specifications
-Compatible Engine Type: 2-Stroke, Single-Cylinder Gasoline Engine
-Target Displacements: Best optimized for 52cc (also compatible with 45cc and 58cc variants)
-Material Base: Anodized Die-Cast Aluminum / Heavy-Duty Alloy
-Aviation Profile Weight: Approximately 110 grams
-Adjustment System: Dual fine-tuning control ports equipped with High (H) and Low (L) speed adjustment needle screws.
-Fuel Feed System: Integrated diaphragm-regulated fuel delivery mechanism.
-Actuation Hookups: Built-in mechanical choke butterfly arm and standard throttle cable return assembly.
Key Features & Product Benefits
-Surface Drive® Anti-Fluctuation Flow: Features a precision-bored interior venturi chamber that keeps fuel atomization stable. This configuration helps eliminate engine bogging, fuel starvation, and RPM fluctuations under dense cutting loads.
-Die-Cast Thermal Performance: The anodized aluminum body dissipates engine block heat quickly. This prevents fuel boil and vapor lock during continuous, high-heat summer operation.
-Accurate Mixture Tuning: The accessible H and L needle screws allow operators to adapt the engine's fuel-air ratio perfectly to changing regional altitudes or specific 2-stroke fuel mix preferences (such as 40:1 or 50:1 ratios).
-Direct Fit Replacement: Built to drop into standard 5200 Chinese chainsaw chassis variants without requiring modification to the existing fuel lines, throttle linkages, or intake spacers.
Installation & Tuning Recommendations
1. Preparation: Clean the area around the air filter box thoroughly before removing the old carburetor to prevent dust or wood chips from falling into the open intake manifold.
2. Sealing: Always install a fresh intake bracket gasket with the pulse hole aligned correctly to ensure an airtight seal against the engine block.
3. Base Calibration: If the engine does not start immediately after installation, turn both the L and H screws fully clockwise until gently seated, then back them out 1.5 turns to establish a reliable baseline start mixture.
