Non ethanol gas

[Gene1949]

One other story. My ’69 RS/SS big block brand X car with a Demon carb (Holly knockoff). Bought a Berry Grant kit. Ran great for a couple of years. One afternoon flooded out at every stop sign. Replaced the gaskets, generally typical Holly problem. Pulled the primary and secondary float valves and the little “O” ring seals on the needle and seat assembly had shrunk and deteriorated.
