The instructor said absolutely don't do it because there have been some engine failures/damage because of it. I don't remember any specifics because it has been over a year since I attended. I just remember the warning. Dick Maddux Kitfox 4 912 UL Pensacola,Fl **************Get a jump start on your taxes. Find a tax professional in your neighborhood today.
