Ethanol is murder on any two cycle engine and on carburetors. In the 70s and 80s they called it gasahol but it flopped until fuel injection came along. Ethanol will separate your oil and gas in in your two stroke engine and eventually you will burn it up. Additives are a necessity if you can't find 100% gas. I'm sure there are a number of places around Gadsden that sell 100% gas. You can buy it in many places in Cherokee County.
