O.S. Engine OS27915000 60B Carburettor Seal Rubber Gasket  [OS27915000]

60B Carburettor Rubber Seal

This O.S. Engine OS27915000 carburettor rubber gasket 60B serves as a replacement sealing piece for RC carburettors, intended to re-establish a reliable rubber seal where required.

By providing an air- and fuel-resistant interface between mating components, the gasket supports steady idle behaviour and consistent mixture settings while tuning. As a consumable item, it should be replaced when fit or elasticity is compromised.

Fitment tips: remove old gasket remnants and any residue before installing the new gasket, take care to centre it without stretching, and tighten screws uniformly to avoid distorting the seal. After reassembly, run the engine briefly to check for leaks and fine tune idle.

Inspection note: check gaskets whenever you service the carburettor; replace at the first sign of hardening, cracking, or compression to keep mixture control reliable.
