Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Mower brand and horsepower alone do not guarantee fit. Use the Briggs engine identification and the listed carburetor numbers.
Frequently Asked Questions
Q: Is this only a bag of gaskets? A: No. Researched listings for these numbers commonly include a complete carburetor plus service items; verify the pictured contents.
Q: Will it fit every Toro Recycler? A: No. Match the engine model/type/code.
Q: Can old gasoline clog a new carburetor? A: Yes. Clean the tank and line before installation.
Q: Why does the mower run only after priming? A: Restricted fuel metering is possible, but fuel flow, intake seal, spark, and compression should also be checked.
