Carburetor Function

The carburetor is responsible for preparing the combustible mixture used by the engine.

During operation, the 545006017 C1U-W32 Carburetor helps:

• Draw fuel from the fuel system
• Meter the appropriate amount of fuel
• Combine fuel with incoming air
• Deliver the mixture toward the engine
• Respond to throttle changes
• Support idle operation
• Support acceleration
• Supply the engine under operating load

Parts documentation describes the purpose of 545006017 as mixing air and gasoline before the combustible mixture enters the engine.

C1U-W32 Carburetor

The specific carburetor designation associated with 545006017 is:

C1U-W32

This designation is important because carburetors that appear physically similar can have different:

• Fuel-metering characteristics
• Linkage configurations
• Primer connections
• Fuel-line connections
• Mounting dimensions
• Internal calibration
• Adjustment specifications

For this reason, the OEM part number should be used to confirm compatibility rather than selecting a carburetor solely by appearance.

Documented Applications

The 545006017 Carburetor Assembly Kit is documented for select:

• Husqvarna string trimmers
• Husqvarna pole saws
• Poulan string trimmers
• Poulan Pro string trimmers
• Poulan Pro pole saws
• Craftsman handheld trimmers
• Husqvarna-manufactured handheld equipment

PartsTree documents the carburetor on multiple Poulan Pro machines, including PPB200E, PP136E, SM446E, PPB32SST, and PPB250E applications.

Other OEM-parts references identify 545006017 as manufactured by Husqvarna for compatible Poulan, Craftsman, and Husqvarna equipment.

Exact compatibility should always be verified using the equipment's complete model and type number.

Common Reasons for Replacement

Replacement of the 545006017 Carburetor Assembly Kit may be appropriate if the existing carburetor has:

• Become internally clogged
• Developed fuel leaks
• Become corroded
• Developed damaged fuel connections
• Become contaminated with old fuel deposits
• Developed damaged diaphragms or internal components
• Become difficult or impossible to properly adjust
• Sustained physical damage
• Developed excessive internal wear
• Become unsuitable for economical repair

A complete carburetor replacement can be useful when cleaning or rebuilding the existing unit does not restore reliable operation.

Possible Symptoms of Carburetor Problems

A worn, clogged, damaged, or improperly functioning carburetor may contribute to:

• Engine will not start
• Engine starts and quickly dies
• Difficult starting
• Engine stalls
• Rough idle
• Engine will not idle
• Hesitation during acceleration
• Poor throttle response
• Reduced engine power
• Engine surging
• Excessively rich operation
• Excessively lean operation
• Fuel leakage

Parts references specifically identify failure to start or starting and then quickly dying as symptoms that can be associated with a failed carburetor.

These symptoms are not exclusive to carburetor failure. Fuel-line, fuel-filter, ignition, compression, air-filter, spark-plug, or other engine problems can produce similar symptoms.

Fuel System Inspection

Before replacing the carburetor, inspect related components including:

• Fuel tank
• Fuel cap
• Fuel filter
• Fuel lines
• Primer bulb
• Air filter
• Intake components
• Carburetor mounting gasket
• Throttle linkage
• Choke linkage
• Spark plug
• Ignition system

Old, hardened, cracked, or leaking fuel lines should be replaced separately as necessary.

Old Fuel & Carburetor Deposits

Fuel left in small-engine equipment for extended periods can deteriorate and leave deposits inside the carburetor.

These deposits can restrict:

• Fuel passages
• Metering circuits
• Needle components
• Fuel inlet passages
• Internal screens

This can cause difficult starting, poor acceleration, unstable idle, or an engine that will not remain running.

Keeping the fuel system clean is important for prolonging carburetor service life. PartsTree specifically recommends keeping fuel free from dirt, debris, and water and avoiding prolonged storage of fuel in infrequently used equipment.

Carburetor Replacement vs. Repair

Depending on the condition of the original carburetor, service may involve either:

Carburetor Cleaning/Rebuilding

• Appropriate when the body remains serviceable
• May involve replacing diaphragms, gaskets, needle components, or other internal parts
• Requires careful cleaning of internal passages

Complete Carburetor Replacement

• Appropriate when the original carburetor is damaged
• Useful when corrosion or wear is extensive
• Can simplify repair when multiple internal components have deteriorated
• Restores the complete carburetor assembly rather than individual internal components

The 545006017 provides an OEM complete carburetor solution for equipment specifically requiring this part number.

Installation Considerations

Before removing the original carburetor:

• Shut off the engine.
• Allow the engine to cool.
• Disconnect the spark plug.
• Drain fuel where appropriate.
• Note the routing of all fuel lines.
• Photograph throttle and choke linkage positions if necessary.
• Clean debris from around the carburetor and air-filter housing.

During installation:

• Connect fuel lines to their correct ports.
• Reinstall throttle and choke linkages correctly.
• Inspect applicable intake gaskets.
• Position the carburetor correctly against the intake.
• Tighten mounting hardware according to the equipment manufacturer's procedure.
• Reinstall the air-filter assembly.
• Check the fuel system for leaks before operation.
