What is included and what will I need for installation?

This kit arrives ready to replace the old carburetor: the package includes one new carburetor and a gasket set, plus a few extra items to simplify reassembly.

How does this replacement affect mower performance?

Replacing a failing carburetor can improve throttle response, idle stability, and cold starts when fuel metering or air‑fuel mixing has degraded. This MOTOALL unit is built to maintain the same flow and mounting as the OEM part, helping the engine run closer to original specifications. However, fuel system cleanliness and correct tune-up also matter for best results.

• Restores proper air‑fuel mixing to reduce stalling and hesitation.
• Direct‑fit design minimizes modification or machining.
• Includes gaskets to ensure fuel and vacuum seals are renewed.

Is the kit compatible with my John Deere mower model?

Yes — this carburetor and gasket kit is listed as compatible with many John Deere lawn mower models that used Briggs & Stratton V‑Twin engines. Confirm your mower’s model and engine specs, since older or uncommon variants may differ. If uncertain, compare the part reference numbers shown on your old carburetor or in the mower’s parts list.

• Compatible John Deere models include L111, L118, L120, LA120, LA130, LA135, LA140, LA145, LA150.
