Sierra 18-0356 Carb Mounting Gasket, Replaces 1347-818620, for Rochester 2 Barrel Carburetors

The Sierra 18-0356 is a carburetor base mounting gasket designed to seal the connection between a Rochester 2 barrel carburetor and the intake manifold. This is the same base gasket that Sierra includes with every one of its remanufactured carburetors, and it is also used together with Sierra Carb Kit 18-7070 when performing a full carburetor rebuild. Installing a fresh mounting gasket during any carburetor removal, rebuild, or replacement is essential to prevent air and fuel leaks at the base of the carburetor, which can cause rough idle, poor fuel efficiency, and inconsistent engine performance.

Each gasket is sold as a single unit and is built to the same fit and material specification as the original equipment gasket it replaces. Because it directly cross-references several OEM and OEM-equivalent part numbers, it is a straightforward drop-in replacement for boat owners and marine technicians servicing Rochester 2 barrel carburetor setups.
