Carburetor Kit 799727 Replacement for Briggs & Stratton 799727 698620 794572 14HP 15HP 16HP 17HP 17.5 HP 18HP,for Craftsman LT1000 Lawn Mower

What It Is

This carburetor kit replaces the OEM Briggs & Stratton 799727 and compatible models (698620, 794572) for 14HP to 18HP single-cylinder engines. It’s designed for Craftsman LT1000 lawn tractors and similar riders using B&S engines in that power range.

Fitment & Compatibility

• Engine model: Must be a Briggs & Stratton with model numbers using 799727, 698620, or 794572. Check your engine’s model/type/spec tag (located under the valve cover or on the blower housing).
• Horsepower: Fits 14HP, 15HP, 16HP, 17HP, 17.5HP, 18HP — but only if the engine model matches. Horsepower alone is not enough.
• Deck size: Not relevant; compatibility is engine-based, not deck size.
• OEM vs aftermarket: This is a non-OEM kit. It may require minor gasket trimming or adjustment to fit perfectly. Compare the old carburetor’s mounting pattern and gasket shape.
• Measure: The carburetor mounting flange width and bolt hole spacing (typically 2.5” center-to-center) to confirm physical fit.

Key Things to Know

• Quality: Mixed reviews. Some report it works fine; others note thin gaskets or slightly different metering holes. Expect to clean or adjust the float height.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, throttle/governor linkage, and fuel line. Label linkages before disassembly.
• Common gotcha: The included gaskets may not match your engine’s intake manifold perfectly. Use your old gaskets if they’re in good shape, or trim the new ones.
• Tuning required: After install, you may need to adjust the idle mixture screw (if adjustable) and ensure the governor linkage is correctly set to avoid surging.

Should You Buy It

If you need a budget fix for a Briggs & Stratton engine in the 14–18HP range and you’re comfortable with minor adjustments, this kit can save you money over an OEM part. But if you want a precise, drop-in replacement with no tinkering, consider the genuine Briggs & Stratton 799727 kit instead.
