OUTSIDE CARBURETOR GASKET 16MM 4-STROKE PART# 05-0504-16 NEW

Isolator rings and gaskets are found between the carburetor and the intake manifold on many 4-stroke units. In many cases when suffering from a lack of performance, the original isolator ring will be cracked and or the gasket will require replacement. If 19mm carburetor then you need a 19mm ring and gasket.
