Carburetor Diaphragm
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 272538S

This is a carburetor diaphragm replacement for use with 3-5 gross HP horizontal crankshaft engines. The diaphragm in a carburetor helps to regulate the fuel in the air-fuel mixture and is an important part of the overall engine. If the diaphragm is bad, owners will notice that the engine does not run smoothly. The machine may not start, or it might suddenly stop in the middle of working. In some cases, the engine might sound sluggish, or it could have an abundance of smoke. When the engine is operating at higher speeds, it could cause it to seem like it could be flooding. These symptoms could indicate that a replacement carburetor diaphragm is needed. During replacement, it is important to make sure the surfaces are clean and dry, and that no solvents or gasket sealer is used. This genuine OEM replacement part is sold individually. The carburetor diaphragm can be used with small engines, tillers, leaf blowers, wood chippers, generators, and lawn mowers. Compatible brands include Briggs & Stratton, Midwest Engine, Craftsman, Toro, and Simplicity.
