Hey, bought the hand-held Husky blower and its turning out to be a great tool. Started okay when new but didn't run that great and did not rev up under load like I expected for the high-velocity blast. I picked up the correct mixture screwdriver for it and after warming it up, I richened the hi-speed needle a little as well as the lo-speed - the hi-speed needle is on the right as usual.

Now it runs perfectly, starts easy, has a fairly quiet muffler and gets the top-end performance I wanted.
