Ethanol can cause problems, but most carb gumming comes from sitting too long, and not properly exercising the gen-set, which will also cause rust on the windings, and rings.
I have had several small engines (some brand new) that have had trouble as a result of ethanol gas. At first I did not know what was causing the issues. When I took them in for repair I was told by the small engine mechanics (that do this for a living) that ethanol laden gasoline destroys modern small engines. They said that the problem is caused because the ethanol can separate in as little as 2 weeks causing water in the tank that will cause corrosion and gumming in the tiny carburetors and glazing on the cylinder walls. They said that 90% of their business now days is repairing small engines that have been destroyed by ethanol gas.
The good thing (at least for me) is I get a lot of small engines for free now days as a result of this. I just convert them to propane and they never have another problem. I got this brand new riding lawnmower for free 2 years ago and have been using it to mow my 2 acre lawn.
