Use a flat-faced punch that is slightly smaller than the plug diameter to gently tap the center of the plug until it flattens out. This expansion creates the interference fit necessary to lock it into the carburetor body.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse a Welch plug after removing it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. Welch plugs are designed to be deformed during installation to create a seal. Once removed, they lose their structural integrity and shape, meaning they cannot provide a reliable, leak-proof seal a second time.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Products From Vendor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/welch-plug-375-til179-55\"\u003e0.375 Inch Welch Plug for Tillotson Carburetor Sealing\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/tillotson-diaphragm-gasket-kit-oem-double-stack-dg-4hl\"\u003eTillotson DG-4HL Diaphragm \u0026amp; Gasket Kit - Double Stack Carbs - OEM Spec\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/brass-screen-tbs\"\u003eHigh-Quality Brass Screen Filter for Tillotson Carburetors\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/adjuster-needle-o-ring-44-361-44-270-tno\"\u003eDurable Adjuster Needle O-Ring for Tillotson Carburetors\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/adjuster-needle-washer-78a-256-tnw\"\u003eTillotson 78A-256 Brass Mixture Screw Washer - High\/Low Side - OEM Carburetor Part\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwiftKarting","offers":[{"title":"Default Title","offer_id":48158088036611,"sku":"TIL179-63","price":4.93,"currency_code":"USD","in_stock":true}],"url":"https:\/\/phishstonesproducts.myshopify.com\/products\/0-500-inch-welch-plug-for-reliable-tillotson-carb-sealing","provider":"PhishStones Products","version":"1.0","type":"link"}
