Ethenol you can thank the tree hugger and the corn farmer's for that crap.
Well which is it?
You have picked two opposing groups. Ethanol is not only more expensive to produce it takes more energy to make it than it does to produce. Monsanto on the other hand stands to gain billions. It is so easy for them because we are so stupid.
For older gas powered equipment (prior to ethanol) the plastics and o-rings will swell in its presents and stop the carb from working properly. You can replace the new carb today (they have made changes) for around $50 or you can get a kit to replace the plastic parts for around $12. Depending on what it is and your skill level buying new may be a better option.
I don't under stand people like you your always wanting to argue about some thing. I have not read any of your post where your not pissing about some thing. Get a life!
