You refuel, drain, and run out of fuel after every use on every piece of equipment?
Got a problem with that?
That's what I do (DEfuel first) unless I'm planning to run it again within a few weeks.
Besides keeping the fuel fresh and free of water, that cleans the tanks of debris that might get into carb if filter falls off or line breaks.
That is a win-win-win, and a total no-brainer, to me. Some of my 2-strokes really heat up the fuel tanks, so they get run dry or defueled after EVERY time out. Another no-brainer. Takes a few seconds.
Only problem I've encountered: the carb diaphragms on my 2 PP saws need to be wetted with fuel for a while after being stored dry for any period of time. So I partly fuel them a day or more before putting them to work, and purge the air from the diaphragm chamber. Member Spike60 has encountered the same phenomenon with some other saws. No biggie if you anticipate it- life in the 21st century with all those Iowa corn squeezings.
How is that possibly harmful? The saws, hedge clipper, brush cutter and leaf blower are fine with that.
