I had the same thing happen to me with my mowers and lawn equipment.I had to replace one and rebuild another carb on my lawn equipment from the crap ass fuel they are shoving up our tail pipes.
The chain saw (new carb and tune up last summer) will not run either. Hit it with starter fluid and it pops right off until it burns all the fluid. Prime indicator the carb is in need of attention. It's a lot of happy horse in my book.
I've been using nothing but ethanol free gasoline in all my lawn stuff for several years.
It's available at the Countrymark station in Lebanon.
Also, here's a website that has listings of stations that sell ethanol free gasoline.
I don't know if it's all inclusive or totally current.
