was gifted this unit and knew it was "cantankerous" when I accepted it. If anyone is familiar with it can you help with explaining the best way to start it once it has been in use and turned off for a few hours? It seems to flood rather easily and once it does I am unable to get it to start no matter what I try. I am also unable to get it to advance trimmer line using the "tap and go" feature. My spool is a single chamber and unless i am incorrect I should wind the line counterclockwise when reloading the spool? No markings to indicate direction of spooling.Thanks for the help.
