What It Is

The Stens Trueblue 146-915 is a 100-foot spool of 9/64-inch diameter starter rope, designed to replace worn or broken pull cords on lawn mowers, trimmers, chainsaws, and small engines. It’s a direct replacement for OEM ropes requiring Size 4 1/2 (9/64” diameter) and is built for high-wear, low-stretch durability.

Fitment & Compatibility

Before buying, confirm your equipment requires 9/64-inch (approx. 3.6mm) diameter rope—this is commonly used on walk-behind mowers, but not on all models. Measure your old rope’s diameter with calipers or check the manual. This rope fits most Briggs & Stratton, Honda, Kawasaki, and Kohler engines using that size, but it’s not brand-specific—it’s a universal replacement. The 100-foot length covers multiple replacements (about 10–15 pulls per mower). Avoid if your machine needs 1/8-inch (3.2mm) or 5/32-inch (4mm) rope—those won’t fit the rope guide or pulley groove.

Key Things to Know

• Quality: Made by an OEM supplier (Stens is a known aftermarket brand), the braided nylon resists fraying and UV damage better than generic rope. Low stretch means consistent pull tension.
• Installation difficulty: Moderate—requires removing the recoil housing, threading through the pulley, tying a knot, and rewinding. No special tools beyond pliers and a screwdriver. Watch a video guide if new to this.
• Common gotcha: The spool is branded, so you get 100 feet—measure your old rope length before cutting. Most mowers use 6–10 feet per pull; cutting too short means starting over.
• Storage: Keep the spool dry to prevent mildew on unused rope.

Should You Buy It

Buy this if you need a reliable, long-lasting replacement for a 9/64-inch starter rope and want a bulk spool for multiple repairs. It’s ideal for DIYers or small engine shops due to the low-stretch build and high wear resistance. Skip it if your mower uses a different rope diameter or you only need a single pre-cut piece.
