” I have two 2-cycle engines. I have had trouble with the fuel lines rotting in both of them.”
Hmm. My chainsaw got a broken fuel line where it went into the tank. Maybe that was rot. My weed eater is acting up. I got replacement fuel lines and a carb rebuild kit for it.
I read up on ethanol-infused fuel. Looks like it was a bad idea. It was done to reduce our dependency on foreign oil.
In mine, the whole fuel line disintegrated.
