591139 Briggs and Stratton Recoil Starter Pull Start Assembly Replacement for Troy Bilt Craftsman TB110 TB200 140CC 150CC Engine Lawn Mower Parts Replace BS 593961 590588 593959 150-012 Rewind Starter

What It Is

The 591139 is a complete recoil starter pull assembly designed to replace the starting mechanism on walk-behind lawn mowers. It fits Briggs & Stratton 140cc and 150cc engines commonly found on Troy-Bilt TB110/TB200 and Craftsman models, allowing you to pull-start the engine when the original starter fails.

Fitment & Compatibility

Before buying, confirm your mower uses a Briggs & Stratton engine with 140cc or 150cc displacement (check engine model number, not mower model). This part replaces OEM numbers 593961, 590588, 593959, and 150-012. Measure the mounting bolt hole spacing—should be 3.25 inches center-to-center. Also check the rope length (typically 48-52 inches) and pulley diameter (approx. 4.5 inches). It will not fit larger engines (e.g., 190cc) or non-Briggs engines like Honda or Kohler. Verify your mower brand: works on most Troy-Bilt TB110/TB200 and Craftsman models with compatible engines.

Key Things to Buy

• Quality: This is an aftermarket part, not OEM Briggs & Stratton. Expect slightly thinner plastic housing and shorter rope life than original. Works fine for occasional use but may wear faster under heavy use.
• Installation: Easy to moderate (30-45 minutes). You’ll need a screwdriver and pliers. Watch for pre-wound spring—it can unwind if you remove the cover. Some units come with rope already threaded; if not, tie a figure-eight knot at the handle end.
• Common Gotchas: The starter cup hook may not align perfectly with your engine’s flywheel fins—check clearance before tightening. If the rope jams, the spring may be mis-seated. Also, the included screws might be slightly different thread pitch than your original; reuse your old bolts if possible.
• Return Policy: Since fitment varies by engine model, keep the packaging until you confirm it mounts correctly. Many sellers require original packaging for returns.

Should You Buy It

Buy this if you have a Briggs 140cc or 150cc engine on a Troy-Bilt or Craftsman mower, need a budget fix for a broken pull start, and are comfortable with basic DIY installation. Skip it if you have a larger engine, want OEM durability for commercial use, or prefer a plug-and-play part with zero fitment risk.
