HUAYI OEM Carburetor Compatible with Troy-Bilt TB30R Riding Lawn Mower Model# 13A726JD066 382cc engine Carb

What It Is

This is an aftermarket carburetor designed to replace the factory unit on a Troy-Bilt TB30R riding mower with a 382cc engine. It meters the fuel-air mixture into the engine for combustion and is a direct swap for the OEM carb on this specific model.

Fitment & Compatibility

• Exact models: Troy-Bilt TB30R (model# 13A726JD066) with the 382cc engine (typically a Briggs & Stratton or similar single-cylinder).
• What to check first: Confirm your mower’s model number (stamped on the frame under the seat or on the hood). Deck size (30-inch) is not a fitment factor—engine model is what matters.
• OEM vs aftermarket: This is a non-OEM (aftermarket) part. It matches the original carb’s bolt pattern and gasket dimensions, but may differ slightly in jetting or finish.
• Measurements: Verify the carb mounting flange bolt spacing (usually 2.5” center-to-center) and intake port diameter (approx. 1”). Compare to your old carb before ordering.
• Kit includes: Carburetor, gaskets, and sometimes fuel line or mounting bolts. Check listing details—some kits omit the fuel filter.

Key Things to Know

• Quality is acceptable for the price – Expect decent performance but not OEM-level longevity. Some users report needing to clean or adjust the carb out of the box.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, screwdrivers) and patience to remove the old carb, swap gaskets, and reconnect fuel lines and throttle linkage.
• Common gotcha: The choke linkage and governor spring alignment can be tricky. Take a photo of the old carb’s linkage before removal.
• Tuning may be required – After installation, you might need to adjust the idle mixture screw (usually 1.5–2 turns out from lightly seated) for smooth running.
• Return policy matters – Some aftermarket carbs arrive with manufacturing debris. Test-fit and inspect before final assembly.

Should You Buy It

If your TB30R is surging, stalling, or won’t start due to a clogged OEM carb, this is a cost-effective fix (under $40) that usually works. It’s a good choice for DIYers who can handle basic carb swapping and tuning, but if you want a guaranteed perfect fit and longer life, spend more on an OEM replacement.
