Our CNC machined Teflon Gasket set may be the last time you'll need to purchase gaskets for your XForce or Zenoah engine. Can be used over again and designed to match the Zenoah G230 and G260 intake manifold and carburetor as well as others with similar port openings. Note: These gaskets can easily be trimmed to modified port openings with a standard razor knife. The carburetor side gasket is bored to .501 and also work with the most  Big Bore carburetors commonly used today.  A couple of  great things about Teflon is that is resists distortion from heat and is not effected by gasoline, so the sealing of both the manifold to the block and the carburetor to the manifold is tight. Both gaskets are equippted with the correct hole locations to activate the internal carburetor pump. Sold as a set (2) only.
