Holy crap, you think that is it?
Ethanol is all we have here. I often have to replace rubber fuel lines here because they rot out after a few years. I have a few running cars that sit many months between uses. I've had to rebuild the carburetors in them a few times.
It is my own fault...I think I'm going to drive them more than I get busy with other things. I should just default to using Sta-Bil in everything that isn't driven a couple times a month.
