Important Notes

• Verify compatibility with your specific Homelite equipment model, UT number, serial number, engine configuration, carburetor type, and production revision before ordering.
• Homelite identifies PS04374 as a Carburetor Adapter Seal / Carb Adapter Seal.
• Match part number PS04374 directly with the number shown in your equipment's illustrated parts diagram or OEM documentation.
• This component is a seal for the carburetor adapter/intake assembly and should not be confused with the carburetor itself, carburetor adapter, intake gasket, cylinder gasket, fuel line, or complete intake assembly.
• Do not select a replacement seal based solely on appearance. Inside diameter, outside diameter, thickness, profile, material, hardness, and engine application can vary between similar-looking seals.
• An intake leak around the carburetor adapter can interfere with proper air-fuel metering and may contribute to hard starting, unstable idle, hesitation, lean running, inconsistent engine speed, or poor performance.
• Similar symptoms can also result from carburetor problems, clogged fuel filters, deteriorated fuel lines, ignition issues, low compression, or other engine conditions.
• Inspect the carburetor adapter, carburetor mounting surfaces, intake components, fuel lines, fasteners, and surrounding seals when replacing PS04374.
• If the original seal is cracked or distorted, inspect the mating surfaces for warping, scoring, corrosion, contamination, or other damage that could prevent proper sealing.
• Clean all applicable sealing surfaces before installing the replacement component.
• Remove dirt, oil, old sealing material, and other debris without damaging the mating surfaces.
• Avoid cutting, stretching, twisting, pinching, or otherwise damaging the replacement seal during installation.
• Install the seal in the same factory position and orientation as the original component.
• Make sure the carburetor adapter and related components are correctly aligned before tightening mounting hardware.
• Tighten applicable fasteners according to manufacturer specifications. Uneven or excessive tightening can damage sealing components or distort mating parts.
• After installation, verify proper engine operation and inspect the intake and fuel system for signs of leakage or improper assembly.
• Gasoline and gasoline vapors are highly flammable. Perform carburetor and fuel-system repairs only with the engine cool and away from flames, sparks, hot surfaces, and other ignition sources.
• This listing is for one Homelite PS04374 Carburetor Adapter Seal only unless otherwise specified. Carburetors, adapters, gaskets, fuel lines, mounting hardware, air filters, and other engine components are sold separately.
• Match part number PS04374 with your equipment's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
