Ryan,
As far as I know there never was a gasket made for the muffler on these old Kohler motors.
And as far as I am concerned they don't need a stinking gasket there just to burn out in a short time, there are enough parts on these 30 plus year old garden tractors that need replaceing after 30 or so years that a simple miffler gasket would be a complete waiste of time, aint like its going to quiet down the ole Kohler any anyhow.
