Help! Onan 4K generator refuses to start and stay on

wopachop, I remember my dad using white gas for our camp stove and its shelf life was great.
Doing what you mentioned using Coleman fuel would probably work for storing a generator during the non-use months due its long shelf life. You would not need to stabilize it. Getting that fuel into the and thru the carb and lines, I think would be good for a very long time. Others in the rv crowd talk about doing that.
