792945 Carburetor For Briggs and Stratton 792945-266 Carb 21HP 22HP 23HP 24HP 25HP 26HP 27HP V-Twin Intek Engine

What It Is

This is an aftermarket carburetor assembly designed to replace the OEM Briggs & Stratton 792945 carb on V-Twin Intek engines found in many riding mowers, zero-turns, and garden tractors from brands like Craftsman, Husqvarna, John Deere, Troy-Bilt, and Murray.

Fitment & Compatibility

• Engine models: Fits Briggs & Stratton Intek V-Twin engines rated 21–27 HP (e.g., 44N877, 44P677, 44R877, 44S877, 44T877). Check your engine’s model/type/code numbers—not just HP.
• OEM vs aftermarket: This is a non-OEM replacement. It may require minor adjustments (idle speed, mixture) and may not include a gasket set—buy one separately if needed.
• Measurements: Verify the carb mounting flange pattern (typically 2-bolt, 3.5" center-to-center). Also check fuel inlet size (usually 5/16" barb) and bowl drain orientation to avoid clearance issues with your engine shroud.
• Deck size irrelevant: Carb fitment depends solely on engine model, not mower deck width.

Key Things to Know

• Quality variance: Aftermarket carbs often work fine but may have slightly different jetting or float settings. Expect to tune the idle mixture screw (if adjustable) after install.
• Install difficulty: Moderate—requires removing the air filter, fuel line, and linkage. Have a small screwdriver set and a 10mm socket handy. Watch for spring clips on throttle/governor arms.
• Common gotchas: The included gaskets may be thin or misaligned—use OEM gaskets if possible. Also, the fuel inlet barb can be brittle; don’t overtighten the fuel line clamp.
• Return policy matters: With a 3.8 rating, some units arrive with debris or sticky floats. Buy from a seller with easy returns.

Should You Buy It

This carb is a budget-friendly fix for a non-starting or surging Intek V-Twin, especially if you’re comfortable with basic carb tuning. Avoid if you want a drop-in OEM replacement with zero adjustments—expect to spend 15–30 minutes dialing it in. Good value for the price if you’re handy.
