Product Details

The Briggs & Stratton 555639 is an OEM main jet designed for use in select Briggs & Stratton carburetors. This blank main jet features no drilled orifice, making it ideal for applications where fuel metering needs to be customized or for blocking off unused jet ports in carburetor bodies.

Key Features:

  • Genuine Briggs & Stratton OEM replacement part
  • Blank configuration with no pre-drilled orifice
  • Precision-manufactured for proper fit and sealing
  • Used for custom carburetor tuning or port blocking applications
  • Designed for specific Briggs & Stratton carburetor models

This blank main jet allows technicians and performance enthusiasts to drill custom orifice sizes for precise fuel delivery tuning, or can be used as-is to block unused jet passages. Always consult your engine's service manual for proper carburetor specifications and jetting requirements.

Quick delivery. Wish I could've ordered all my needed tv vent parts from you.

My order for the Ram third brake light camera was shipped quickly and received in great shape. I'm looking forward to installing it this weekend.

It was nice and easy to order

To soon to tell

All good.
