diaphragm gasket
A diaphragm gasket is a thin, flexible plate located in the intake port of a two-stroke engine. It acts as a check valve: the air-fuel mixture enters through it but cannot flow back to the carburetor. Without a properly functioning diaphragm gasket, you lose power and your engine runs irregularly or idles poorly.
When choosing, pay attention to the engine type and block of your scooter or moped — whether it is a Puch Maxi, Tomos, Piaggio, or Yamaha Minarelli, every engine requires a specific size and version. On this page, you will find a wide range for the most common two-stroke engines, so you can quickly find the right gasket for your machine.
