I have a Stihl backpack blower. What do you all do to keep the blower tube from falling out of the blower all the time? I'm thinking of bolting it to the blower, but the end of the blower tub has a curved nozzle and I turn the tube frequently to blow the leaves or clippings different directions. Should I just bolt it to the blower tube and leave off the curved portion of the nozzle? What do you all use: Curved blower tube end or Straight?
