Product Details

The Sierra 18-7666 Choke Pull-Off is a high-quality replacement vacuum choke pull-off (also known as a choke vacuum break or choke diaphragm) designed for marine carburetor applications. This component plays a critical role in the cold-start enrichment system by partially opening the choke plate after initial engine startup, preventing the engine from running overly rich and reducing stalling and rough idle during warm-up.

Key Features:

  • Direct-fit replacement for OEM choke pull-off assemblies
  • Engineered to Sierra's marine-grade quality standards
  • Restores proper choke function for reliable cold-start performance
  • Durable diaphragm construction resists fuel vapors and marine environment exposure
  • Helps prevent engine flooding and rough running during warm-up cycles

Sierra International is a trusted aftermarket brand in the marine industry, producing parts that meet or exceed OEM specifications. The 18-7666 choke pull-off is an ideal solution for restoring proper carburetor operation on inboard and sterndrive marine engines. Always verify fitment against your engine's service manual or OEM part number before installation.
