Compatible with Most Walk-Behind Mowers, SL-305 Throttle Control Cable with 48" Conduit & 54.5" Inner Wire Smooth Throttle Response

What It Is

This SL-305 throttle control cable is a universal replacement part for walk-behind mowers, connecting the throttle lever to the engine carburetor to control engine speed. It’s designed for smooth throttle response and is suitable for standard residential mowers, not zero-turn or ride-on machines.

Fitment & Compatibility

Before buying, measure both the conduit length and inner wire length. This cable has a 48-inch conduit and a 54.5-inch inner wire (including end fittings). Check your mower’s old cable: the conduit must be roughly the same length to reach from the handle to the carburetor without excess slack or tension. Measure from the throttle lever bracket to the carburetor anchor point, then add a few inches for routing.

This is a universal part, so it may fit most walk-behind mowers with a standard throttle cable setup. However, verify that the end fittings match: the carburetor end typically uses a barrel or loop, and the lever end uses a threaded barrel or clip. If your mower has a specialized bracket (e.g., on some Honda or Toro models), the cable might not lock in securely. No specific brand or model list is provided—assume compatibility with generic 4-stroke engines like Briggs & Stratton, Tecumseh, or Kawasaki.

What to check:

• Conduit length (48″)
• Inner wire length (54.5″)
• End fitting types
• Carburetor anchor design (hole size, clip style)

Key Things to Know

• Installation difficulty: Moderate. You may need to remove the old cable, route the new one, and adjust the cable tension at the carburetor. Expect 15–30 minutes if you’re handy.
• Quality: At $16.99 with a 5.0 rating (2 reviews), this is a budget-friendly aftermarket part. It may not be as durable as OEM cables, but it’s fine for occasional use.
• Common gotcha: The 54.5″ inner wire is slightly longer than many OEM cables (often 50–52″). This extra length can cause slack if your mower’s routing is short. You may need to cut the inner wire (use a Dremel or wire cutter) and re-crimp the end fitting—or simply adjust the tension at the carburetor bracket.
• Smooth throttle response is claimed, but actual feel depends on cable routing and friction. Lubricate the cable lightly with WD-40 or cable lube before installation to reduce binding.

Should You Buy It

This cable is a good fit if you need a cheap, universal replacement for a standard walk-behind mower and you’re comfortable with a little DIY adjustment (cutting/crimping the wire). It’s not ideal for exact OEM replacements or for mowers with unique end fittings. If you want a drop-in fit without modifications, measure twice and consider spending more on a brand-specific cable. For the price, it’s a solid budget option for experienced tinkerers.
