Walbro Carburetor Welch Plug OEM Replacement

Genuine Walbro carburetor Welch plugs (also called welsh plugs, expansion plugs or freeze plugs) are OEM replacement parts. They seal the machined passages and wells in Walbro carburetors. Over time, vibration or deposit build-up can loosen a Welch plug and break its seal. A loose plug can cause fuel and air leaks, poor idle and hard starting, and it can disturb engine tuning. Replacing it with a genuine Walbro plug restores a tight seal.

Key Features:

• Genuine OEM Walbro replacement part
• Seals the carburetor's internal passages and metering wells
• Made for Walbro carburetors used on small engines, including 2-cycle equipment such as chainsaws, trimmers and blowers
• Domed, cup-style plug that is flattened in place to expand and seat in the bore
• Choose the child item that matches your carburetor's plug

Installation notes: Remove the old plug by carefully piercing it at a shallow angle and prying it out. Take care not to damage the bore underneath. Seat the new plug with a flat-faced punch slightly smaller than the plug, and strike it gently until the crown is flat. Do not cave it in. Walbro carburetor service tools are made for this job.

Choosing an OEM Walbro Welch plug helps keep your carburetor sealed and performing as designed.
