85% ethanol is a problem for ANY lawn mower engine!
There isnt a single piece of lawn equipment made to run on any amount of alcohol. Let alone run on something with 85% ethanol in it!
You should drain the tank and carb and put in clean, fresh, non-oxygenated alcohol-free fuel.
Ethanol and methanol ruin a lot of the materials that lawn mowers are made out of. So you might be stuck doing a carb replacement along with changing out all the fuel lines and related items.
