Exmark 136-7840 136-7842 127-9289 74657 Carburetor

Exmark 136-7840 / 136-7842 / 127-9289 / 74657 compatible carburetor is a direct-bolt-on small-engine fuel-delivery assembly manufactured as an OEM or aftermarket replacement for gasoline 4-stroke engines found in Exmark Quest E-Series/S-Series and Toro Time Cutter riding mowers. It regulates the air-fuel mixture to ensure stable starting, idle control, and load performance by delivering consistent fuel atomization, with an aluminum carb body that houses the float and jet system. This carburetor is commonly used on Toro Time Cutter zero-turn mowers and Exmark Quest E-Series and S-Series models, and is suitable for Titan HD riding mowers where precise fuel-air mixing is required for Kohler and Kawasaki engine variants. Mounting is a direct bolt-on to the intake manifold; fuel type is gasoline with ethanol-compatible variants depending on model; operation is a mechanical float-type carburetor. The kit typically includes the carburetor itself, with some listings offering gaskets, fuel pump, and filters, and is intended for outdoor power equipment and lawn maintenance machinery. Common replacements include Toro OEM carburetor assembly (Time Cutter 136-7840 series), Kohler small engine carburetor equivalent (mower-specific fitment), and Briggs & Stratton aftermarket carburetor assembly (similar small engine class).
