Good question. My experience has been the manufacturers aren't doing much, if anything to qualify their products for Ethanol. If they have a problem they will address it. Otherwise, most seem content to let it ride. I am aware of some aircraft engine manufacturers like Rotax and others who have commented and are generally accepting of ethanol up to 10%. I know of no manufacturer who recommends the use of ethanol, though.
Ok. Thanks. Some jurisidictions don’t offer you the option of having gas without ethanol.
IIRC, the bugs were not originally built with catalytic convertors. Do they need to be installed, or have most of the used ones you’ve found already have them installed?
