Throttle Cable Kit 21243 Compatible for Multiquip-Whiteman J36, JS36, B46, BS46 Trowel

What It Is

This throttle cable kit (model 21243) controls engine speed on Multiquip-Whiteman walk-behind power trowels, specifically the J36, JS36, B46, and BS46 models. It replaces a worn or broken cable assembly to restore smooth throttle operation.

Fitment & Compatibility

Before buying, confirm your machine’s model number (e.g., J36, JS36, B46, or BS46) – this cable does not fit other Whiteman or Multiquip trowels. Measure your existing cable’s overall length (housing to end of wire) and compare to the OEM part (usually ~36–40 inches). This is an aftermarket replacement, not OEM, so check that the mounting bracket holes and end fittings (e.g., ball joint or barrel) match your throttle lever and engine carburetor. The listing’s 2 reviews suggest it fits the stated models, but verify with your specific serial number if possible.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, pliers) to remove the old cable and route the new one. Expect 20–40 minutes.
• Quality: Aftermarket, so materials and feel may differ slightly from OEM. The 5.0 rating (2 reviews) is promising but limited – inspect the wire for fraying before installing.
• Common gotcha: The cable may be slightly longer or shorter than the original. Adjust the throttle lever travel or add a zip tie to secure excess housing. Test full range (idle to full) before final tightening.
• No adapter included: You may need to reuse your old cable’s mounting nuts or grommets if the kit doesn’t include them.

Should You Buy It

If you need a budget-friendly replacement for a worn throttle cable on a Whiteman J36, JS36, B46, or BS46 trowel, this kit is a solid choice at $16.99 – just verify fitment with your machine’s model and measure your old cable first. For other trowels or OEM-only preferences, look elsewhere.
