Zama Welch Plug for Carburetor Repair

Zama Welch Plugs are small metal expansion plugs used for carburetor repair and rebuilds. Also called welsh plugs, freeze plugs, core plugs, or expansion plugs, they seal the machined passages and drilled openings in a carburetor body. When a carburetor is cleaned, the old plugs are often removed to reach the passages behind them. Fresh plugs then restore a proper seal.

Key Features:

• Seals open passages and drilled access holes in carburetor bodies
• Helps keep fuel and air circuits sealed and correctly routed after a rebuild
• Suits small-engine carburetor repair and overhaul work
• Made by Zama, a well-known name in carburetors and carburetor components
• Available in multiple variants so you can match the plug to the carburetor you are working on

Replacing worn, corroded, or removed welch plugs during a carburetor rebuild helps prevent fuel leaks and vacuum or air leaks. This supports smooth idle, steady throttle response, and reliable engine performance. Choose the variant that matches your carburetor's plug openings.
