This genuine OEM sourced replacement part is specially designed for Briggs and Stratton engines commonly installed on lawn and garden equipment. The purpose of this part is to mix the air and the gas before the combustible mix goes to the engine, over time components may wear out and begin to fail eventually requiring a replacement to ensure peak performance. If the engine won't start and the tank is full of fresh fuel or if the engine starts and then quickly dies, the carburetor is likely the problem. Please note this high-quality metal body carburetor is sold individually, keep in mind it also includes a rubber hose and a composite material gasket.

Solenoid had gone out and carburetor misfiring

Was extremely easy. Only got the whole carburetor because it was cheaper than buying the solenoid and rebuilding carb. 4 bolts and the throttle and choke levers were easy to remove and replacement was just as easy. From opening box to firing up mower took all of 15 minutes and new carb fit like a glove. Nothing special or hard about it. Just remove the 4 bolts first and it makes it easier to remove the throttle and choke levers with springs.
