When to Replace

A worn or restricted carburetor and related fuel-system components can contribute to rough or inconsistent running, failure to start, or fuel leaks. Replacing the carburetor, primer bulb, fuel lines, gaskets, filters, and spark plug together can address common tune-up needs when these parts are worn or contaminated.

Installation Tips

  • Verify the blower model and version code before disassembly.
  • Compare the replacement carburetor and fuel-line routing with the removed components.
  • Replace the sealing gasket during installation to help prevent air or fuel leaks.
  • Install the included primer bulb, fuel lines, fuel-line joints, fuel filter, spark plug, and foam air filters as needed.
  • Inspect all connections for secure seating and fuel leaks before operating the blower.

Package contents: 1 carburetor, 1 primer bulb, 2 yellow fuel lines, 2 fuel-line joints, 1 gasket, 1 spark plug, 1 fuel filter, and 2 foam air filters.

FAQs

This kit is designed for the Ryobi RY25 25cc 2-cycle leaf blower, including model RY25AXB. Verify the identification label and existing carburetor before ordering.
It replaces Walbro WYJ-533 and Ryobi part number 308054121.
Common symptoms include hard starting, stalling when the throttle is opened, poor acceleration, surging, reduced blowing power, fuel leakage, or an engine that will only run with the choke partially engaged.
Use fresh 2-cycle fuel mixed to the engine manufacturer's specified ratio, and inspect the fuel hose, fuel filter, primer components, air filter, and spark plug. Contaminated fuel or a restricted filter can cause symptoms that resemble a carburetor problem.
Installation generally requires basic screwdrivers, small pliers, and a clean work area. Allow approximately 30 to 60 minutes, depending on access and whether the fuel lines or related components also need attention. Disconnect the spark plug wire and drain the fuel before starting.
