Re: Vitron Rubber Tipped carburetor Needle

Viton (not vitron) is a registered trademark for a series of synthetic rubbers made from vinylidene flouride and hexafluoropropylene and hence is related to the "teflon" family. I don't know if those materials are still used in inlet needles but they have excellent mechanical properties and are inert to gasoline and most solvents, alcohols included I believe. Though Viton was widely used for decades for inlet needles and was considered superior to the all-brass sets, perhaps something about modern gasoline other than ethanol has caused some incompatibility? Probably a phone call to Daytona Parts would give a definitive answer, but personally I'd also prefer an all-metal needle and seat.
