594062 Recoil Starter Pull Start Assembly Rewind Starter for B&S 103m02 103m05 104m02 Lawn Mower

What It Is

This is an aftermarket recoil starter assembly that replaces the pull-start mechanism on Briggs & Stratton engines, specifically designed for the 103M02, 103M05, and 104M02 series. It’s used to rewind the starter rope and engage the engine flywheel for pull-starting walk-behind mowers, small tractors, or other equipment with these engines.

Fitment & Compatibility

Check your engine’s model number—must be 103M02, 103M05, or 104M02 (found on the engine shroud or valve cover). This part is aftermarket, not OEM, but matches the original dimensions. Measure the bolt spacing (typically 2.75 inches center-to-center) and the starter pulley diameter (usually 3.25 inches) to confirm fit. It will not work on engines outside this series, like the 100M or 110M models. Also verify your old starter has three mounting bolts; some older versions use two.

Key Things to Know

• Quality vs. OEM: Expect slightly thinner plastic housing and rope compared to a genuine Briggs & Stratton part, but functional for typical home use. Rope may fray faster under heavy use.
• Installation difficulty: Easy—remove two or three bolts, disconnect the old starter, install new one, and reattach. No special tools needed. Watch for the spring tension; the new unit comes pre-wound.
• Common gotcha: The rope length is pre-set (usually 48 inches). If your mower needs a longer pull, this won’t adjust. Also, the starter cup may need a thin washer if it’s loose on the crankshaft.
• Return policy: Since it’s aftermarket, test fit immediately; some units have minor molding flaws that cause binding.

Should You Buy It

If your current recoil starter is broken (rope snapped, spring popped, or pulley cracked) and you have a 103M02/05 or 104M02 engine, this is a budget-friendly fix that works for occasional mowing. It’s not for daily commercial use or engine swaps—stick with OEM if you need durability. For $20, it’s a solid value if you confirm fitment first.
