Installing the intake gasket on a Ryobi trimmer The Facts

Trimmer out of whack? It's time to face the fix. Whether you are a legendary landscaper or a weekend weed whacker, eReplacementParts.com provides the parts, procedures and facts you need to fearlessly fix what fails you.

The intake gasket creates a seal between the engine block and the heat dam (behind the carburetor). This gasket usually only needs to be replaced when it is removed as part of another engine repair. If the gasket is torn when it is removed, it must be replaced.

The only way to ensure a proper seal is to replace the gasket every time it is removed. A leak in the intake gasket will allow extra air into the cylinder. If the leak is bad enough, you will notice the engine surging erratically. It will be hard to start and die randomly. The RPM will climb and fall while the engine is running.

An air leak is a serious problem. It can cause the engine to run lean, which will lead to scarring on the piston and cylinder, and eventually, a seized engine. If you suspect your engine has an air leak, you should stop using it immediately.
