Parts for Briggs & Stratton 226437-1005-E1: Carburetor Assy Parts

This is a small adjustment screw used in lawn mower engines to regulate idle speed. It threads into the carburetor assembly and controls the amount of air or fuel mixture at idle. Replace this screw if it is stripped, corroded, or if the engine idle speed cannot be properly adjusted.

Here is a replacement carburetor float for small engines used on lawn mowers and other machines. The carburetor combines air and fuel, ensuring that the engine has the right mix for combustion and performance. The carburetor float plays a critical role in that process by helping to ensure that the optimum level of fuel stays in the chamber. As the fuel level rises and falls, the float does as well, operating the fuel needle and replenishing or slowing the supply of gasoline. Over time, carburetor floats can degrade due to exposure to gasoline and high temperatures. A sticking carburetor float is a sign that it needs to be replaced. The engine may sputter, may rev high, or may choke itself out. Replacing the carburetor float will require removing the air box, the air cleaner element, the fuel line, and the carburetor itself. The carburetor bowl must be removed to access the old float and replace it with a new one. Note that this is a new OEM carburetor float designed to fit Briggs & Stratton engines on over 150 different yard machines from brands like Murray, Toro, and Lawn-Boy. It is sold individually.

Fix engine stalling or rough running caused by fuel delivery issues. This float bowl mounts to your carburetor and regulates fuel supply to the engine.
