Are any of your small engines designed or specifically converted to run on E85? Or are you using some lower ratio of ethanol to gas? In any case, small engines like those in lawnmowers are more of an effort to get running properly because, unless something's changed, they're not using an ECU or lambda sensors that would allow them to change the fuel trim (I'm probably speaking the obvious here so forgive me). They usually have to be re-jetted and maybe have their timing manually advanced.
