What It Is

This is a replacement carburetor for Troy-Bilt, MTD, and Yard Man push mowers with Briggs & Stratton engines in the 130–190cc range. It controls the air-fuel mix into the engine; if your mower won’t start, runs rough, or stalls, this is a common fix.

Fitment & Compatibility

Check your engine model, not just the mower model. This carb fits specific Troy-Bilt/MTD/Yard Man models listed (e.g., 11A-542Q711, 11A-B29Q711, 11A-5490755, 11A-422Q713, 11B-439Q755, 12A-568Q701, 12AVD39Q701, 11A-B29Q701, 11A-588Q795). But it’s also compatible with many Briggs & Stratton engines on these mowers—look for a “Briggs & Stratton” nameplate and engine displacement between 130cc and 190cc.
Measure your old carb: Ensure the mounting flange bolt spacing is ~2.5 inches center-to-center and the fuel inlet nipple diameter matches your fuel line (usually 1/4-inch). This is an aftermarket carb, not OEM, so gaskets and seals may be thinner—expect to reuse your original gaskets if the supplied ones don’t seal well.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (socket set, screwdriver, pliers). Expect to remove the air filter housing, fuel line, and throttle linkage. Take photos before disassembly for reattachment.
• Common gotcha: The supplied gaskets are often too thin or poorly cut. Reuse your original gaskets or buy a separate gasket set for a reliable seal—fuel leaks here cause hard starting.
• Quality variance: ~4.3 stars from 274 reviews suggests most work out of the box, but expect a small chance of debris in the carb bowl or a misaligned float. Clean it thoroughly before install.
• Tuning required: You may need to adjust the idle speed screw (usually on the side) after installation to prevent stalling or racing.

Should You Buy It

Buy this if your mower matches the listed models and you want a budget-friendly fix for a non-starting or rough-running engine. It’s not OEM, so skip it if you need exact factory parts or aren’t comfortable tweaking a carb. For $23, it’s a solid gamble for DIYers who can handle minor adjustments.
