I was wondering what type of fuel is recommended in the 27hp liquid cooled gas Kaw engine on the LazerZ? Is there any advantage to regular unleaded fual or ethanol blend fuels for the engine? Have heard some negative comments about ethanol blend fuels in vegicles but that is just hear say so don't put much stake in what I have heard. Would like to know what eXmark has to say on the subject of which is better to use; ethanol blend or regular unleaded. Thanks for any comments!
