Ethanol DOES NOT pit metal. If the bowl on your machine was pitted, it was from the WATER that is attracted to the alcohol in the fuel. I've said this a million times on here, and I'll say it again. I run ethanol blended fuel in all my cubs. I NEVER shut the gas off on any. Just dug one out that had been sitting for at least 6 weeks. Gas was on, no leaks, it was fine. For the record, not all needle valves are rubber tipped. Some are all brass. Ethanol has it's problems I don't disagree. It does eat rubber that isn't made for it. But, the manufacturers are aware and new products that are compatible are out there. More all the time. You really don't need to push blame to ethanol where the actual problem is improper general maintenance and mostly older non-compatible parts.
