Found this manual - but unsure if your engine predates the 32cc they cover. DLA%20Operating%20Manual%20Current.pdf

They warn about ethanol OVER 10%, so presumably you will be fine. I'm running some other brands that use Walbro carbs that are over 20 years old, that have no issues with 10%. Here in the US, ethanol has been in use in some areas for a very long time now (since 1997 in my state), so things have to be really old to be incompatible. But there are still many that don't trust it, so are always looking for a place that sells "pure" gas. The warning about moisture is valid though - so keep what you have for airplane use fairly fresh (ie - one season, not stored over the winter).
