LT1000 Carburetor Replacement for Briggs Stratton 17.5 I/C OHV Engine Lawn Mower 697203 697141 697216

What It Is

This is an aftermarket carburetor replacement for Briggs & Stratton 17.5 I/C OHV (Industrial/Commercial OverHead Valve) engines, typically found on riding mowers and tractors. It directly replaces OEM part numbers 697203, 697141, and 697216, restoring fuel delivery and engine performance when the original carburetor clogs, leaks, or fails.

Fitment & Compatibility

Before buying, check the following:

• Engine model: Confirm your engine is a Briggs & Stratton 17.5 I/C OHV (not a different displacement or series). Look for model/type numbers stamped on the valve cover or blower housing.
• OEM cross-reference: This carb matches 697203, 697141, and 697216. If your original part number is different, measure mounting bolt spacing (usually 2.5" center-to-center) and fuel inlet orientation.
• Deck size / tractor brand: Fits most lawn tractors with this engine (e.g., Craftsman, Husqvarna, MTD, Troy-Bilt), regardless of deck size. But verify the throttle/choke linkage style matches your mower (some have plastic, others metal linkages).
• Gaskets included: Kit usually comes with gaskets and a fuel line filter. Ensure your mower uses a standard bowl-type carb (not a side-draft or EPA-compliant model with different fittings).

Key Things to Know

• Aftermarket quality varies: At this price point, the carb may need minor adjustments (idle screw, float height) out of the box. Expect plastic parts instead of metal on the OEM. Fine for budget repairs, but not as durable.
• Installation difficulty is moderate: Requires removing the air filter, fuel line, and throttle/governor linkages. Take photos before disassembly. No special tools needed beyond a socket set and screwdriver.
• Common gotchas: The fuel inlet barb may be slightly different diameter (8mm vs 6mm) – you might need a short fuel line adapter. Also, the choke linkage can be reversed; test before tightening.
• Return policy matters: With only 3 reviews, reliability is unproven. Buy from a seller with a solid return policy in case of defects or fitment issues.

Should You Buy It

If you have a Briggs 17.5 I/C OHV engine and need a cheap, quick fix for a non-starting or rough-running mower, this carb is a solid budget option. It’s ideal for DIYers comfortable with basic carb tuning and linkage adjustments. However, if you want guaranteed fit and longevity (especially for commercial use), spend more on an OEM or known-brand replacement.
