corporalk,
The thermal isolation gasket, IH-117201-C1 USE KH-47-049-01 is about $16.00 and is available from our sponsors and from other cub parts supply houses. It’s purpose is not only to help keep the carb and thus fuel cooler but also to help prevent dirt from being drawn into the intake, one of the primary causes of premature engine wear.
I'd buy it.
