What It Is

This is an aftermarket carburetor kit for Toro 21442, 21321, and 21352 mowers with 140cc or 150cc GTS engines, plus Craftsman M110 and CMXGMAM1125499 models. It includes the carburetor, air filter, and cover—everything needed to replace a clogged or failed fuel system on small push mowers.

Fitment & Compatibility

• Direct fit for: Toro 21442, 21321, 21352 (140cc/150cc GTS) and Craftsman M110 / CMXGMAM1125499.
• Check engine model: Must be a 140cc or 150cc GTS engine (Toro) or the specific Craftsman model number. Not for larger engines or non-GTS Toro variants.
• OEM vs aftermarket: This is a non-OEM replacement. Measurements match the original, but verify your carburetor mounting pattern (two-bolt flange, typical 1.5" spacing) and fuel inlet orientation.
• What to measure: Compare the old carburetor’s bowl diameter and gasket shape to the included one. The air filter cover must align with your mower’s housing—check that the filter element fits snugly.

Key Things to Know

• Quality: Generally good for the price, but some units may need a minor gasket trim or adjustment of the idle screw. Clean any debris from the new carb before installing.
• Installation difficulty: Moderate. You’ll need to drain fuel, remove the old carb, and reconnect the throttle linkage and fuel line. A small Phillips screwdriver and a 10mm socket are typical.
• Common gotcha: The included air filter may be slightly different thickness than OEM—test fit before reassembling the cover. If the engine runs lean, adjust the idle mixture screw (1.5 turns out is a safe starting point).
• Includes: Carburetor, gaskets, air filter, cover, and mounting hardware. Does not include fuel line or clamp.

Should You Buy It

If your Toro 140cc/150cc GTS or Craftsman M110/CMXGMAM1125499 is hard-starting, surging, or won’t run, and you want a budget-friendly fix that includes the air filter cover, this kit is a solid choice. It’s best for DIYers comfortable with basic carburetor replacement—skip it if you need OEM exactness or have a different engine model.
