Our CNC machined Teflon Gasket may be the last time you'll need to purchase gaskets for your 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. This 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 the carburetor to the manifold is tight.  The gaskets are equipped with the corect hole locations to activate the internal carburetor pump. Sold as one only.
