It is an authentic OEM supplied exhaust gasket that is designed to provide an air tight seal between the muffler and the exhaust pipe. This part is specially produced for use with Briggs and Stratton engines commonly installed on Toro lawn and garden equipment. Over time gaskets tend to shrink, become brittle and crack eventually requiring replacement. It is made of high-quality composite material and it is sold individually.

The engine on my log splitter would only stay running with the choke on, every time I turn the choke off the engine would die.

Remove air cleaner, there are three screws that hold the back plate on remove them, the gasket may stick to the carburetor so you will have to clean the old gasket off, the new part that I got is universal so I had to cut off a tab which was not hard at all. Put the new backplate on and put the air cleaner back on.

These items did not fix my problem. What really fixed the problem was a good cleaning of the carburetor bowl and jet plug.
