What It Is

This is a carburetor tune-up kit designed to restore fuel delivery in Briggs & Stratton engines (models 28D707, 28M707, 28R707, 289707, 28D702) found on Toro 71301 lawn tractors and other 12–13 HP mowers. It replaces OEM part 694941 and includes gaskets, seals, and a carburetor rebuild components to fix rough idling, stalling, or hard starting.

Fitment & Compatibility

• Engine models only: Fits Briggs & Stratton single-cylinder engines with model numbers starting with 28D707, 28M707, 28R707, 289707, or 28D702. Check your engine’s model number (stamped on the blower housing or valve cover)—not the mower deck size.
• Mower models: Directly compatible with Toro 71301 and similar Toro lawn tractors using these engines. Not for walk-behind mowers or zero-turn models.
• OEM vs aftermarket: This is an aftermarket kit replacing Briggs & Stratton part 694941. Quality is generally good, but OEM gaskets may have slightly tighter tolerances.
• Measurement check: Kit includes no carburetor body—only internal parts like float, needle, gaskets, and jets. Ensure your carburetor is physically intact before buying.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (screwdrivers, socket set) and carburetor cleaner. Not for beginners who haven’t removed a carburetor before.
• Common gotcha: The fuel bowl gasket may not perfectly match every variant of these engines. Compare the old gasket before installing.
• Quality note: Some users report the included jets are slightly smaller than OEM, which can lean out the fuel mix. If you notice surging after install, re-use the original jets.
• What’s missing: No fuel filter or spark plug is included—buy those separately if needed.

Should You Buy It

If your Toro tractor engine is hard to start, runs rough, or dies under load, and you’re comfortable disassembling and cleaning a carburetor, this kit is a cost-effective fix. It’s not for complete carb replacement or for engines outside the listed model range. For a quick, reliable repair on a 10+ year-old mower, it’s a solid value.
