Tillotson 80-332 Body Channel Cup Plug

The Tillotson 80-332 is a body channel cup plug (also known as a Welch plug) designed for use in Tillotson carburetor bodies. This precision-manufactured plug seals internal fuel and air passages within the carburetor body, providing access to critical internal channels during carburetor rebuilding and cleaning procedures.

Key Features:

• 0.1875 inch (3/16 inch) diameter body channel cup plug
• Seals machined passages in carburetor body castings
• Used in various Tillotson HU-Series and HL-Series carburetors
• Essential component for proper carburetor rebuilding
• Provides access to internal fuel passages for thorough cleaning

This cup plug is installed during carburetor assembly to seal off the body channels drilled during manufacturing. When performing a comprehensive carburetor rebuild, removing and replacing this plug allows access to clean varnish and debris from internal passages that cannot otherwise be reached. Proper installation requires pressing the plug into place and flattening it slightly to create a secure seal.
