KINDZA Flywheel Cup Engine Recoil Starter for Briggs & Stratton 593960 593959 08P502 Black

What It Is

This aftermarket flywheel cup and recoil starter assembly replaces the original Briggs & Stratton starter on small engines (typically push mowers, tillers, or generators). It’s designed to engage the engine’s flywheel when you pull the cord, spinning the crankshaft to start the engine.

Fitment & Compatibility

• Direct OEM replacement for: Briggs & Stratton part numbers 593960, 593959, and 08P502 (black version).
• Engine series: Fits many Briggs & Stratton single-cylinder engines with a 3.5–6.5 hp range, including models like 08P502, 09P702, 10T502, 12H802, and 12A902. Check the engine model number (stamped on the blower housing or valve cover) to confirm.
• Measurements: The cup diameter is approximately 5.5 inches (140 mm), and the bolt pattern is 2.75 inches (70 mm) center-to-center. Measure your existing cup before ordering.
• Not compatible with: Engines using a different starter cup design (e.g., Tecumseh, Honda, or older B&S models with a different bolt pattern). If your engine has a 4-bolt starter mount, this won’t fit.

Key Things to Know

• Quality: Users report it’s a functional, budget-friendly alternative to OEM. Some note the plastic is slightly thinner than the original—handle with care during installation.
• Installation difficulty: Easy—requires only a socket wrench and basic mechanical skill. Remove the old cup (may need a puller if stuck) and bolt this one on. No wiring or special tools.
• Common gotcha: The included recoil spring may need slight pre-winding before attaching the rope. If the spring pops out, reassembly is fiddly but doable.
• Rope length: The starter rope is typically pre-installed at about 24 inches. If your engine needs longer, you can replace the rope easily.

Should You Buy It

If your Briggs & Stratton engine’s starter cup is cracked, the recoil is dead, or the pawls are broken, this $7.25 part is a solid, low-risk fix. It’s right for DIYers who want to save money over a $30+ OEM part and don’t mind a slightly less robust build. If you need a heavy-duty replacement for commercial use, stick with OEM.
