Cnfaner Carburetor for Husqvarna HU700F HU700H 7021P, for Troy-Bilt TB240 TB130 130XP Lawn Mower

What It Is

This is a direct-fit aftermarket carburetor designed to replace the factory unit on specific Husqvarna and Troy-Bilt walk-behind mowers with Briggs & Stratton or similar single-cylinder engines. It meters the air-fuel mix for combustion and is intended for models with 140cc–190cc engines used in residential lawn care.

Fitment & Compatibility

• Brand/Model: Fits Husqvarna HU700F, HU700H, 7021P, and Troy-Bilt TB240, TB130, 130XP.
• Engine Check: Verify your mower’s engine model (e.g., Briggs & Stratton 450E, 500E series). This carburetor typically fits engines with a vertical shaft and a 3.75–5.5 ft-lb torque range.
• OEM Reference: Replaces OEM parts like Husqvarna 532187605, 187605, or Troy-Bilt 753-05948. Cross-check your old carburetor’s number.
• Physical Fit: Measure the mounting bolt spacing (usually 2.5 inches center-to-center) and the fuel inlet diameter (¼ inch). Some models require a separate gasket (not included).
• Deck Size: No direct link to deck size; compatibility depends solely on engine model, not cutting width.

Key Things to Know

• Quality: Aftermarket—may need minor tuning (idle screw adjustment) for optimal performance. Some users report air leaks if gasket isn’t replaced.
• Installation: Moderate difficulty (30–60 min). Requires removing air filter, fuel line, and throttle cable. Clean the fuel tank and line before installing to avoid debris clogging.
• Common Gotchas: The included bolts are often too long; reuse your original ones. Float height may be off—check it’s level (typically 0.125–0.150 inches) before mounting.
• Fuel Compatibility: Works with standard unleaded gas (E10 okay) but not ethanol-free or high-octane race fuel.

Should You Buy It

Buy this if you have a compatible Husqvarna or Troy-Bilt mower with a clogged or failing original carburetor and want a low-cost, functional replacement. It’s not OEM quality, so expect some adjustment—ideal for DIYers comfortable with basic engine work. Skip it if you want plug-and-play perfection or have a high-hour mower needing a full carburetor kit rebuild instead.
