Saw Dr.
Junk Collector
OK, so maybe it is not a saw, but I am finally stumped. Husky BT-380 strato backpack blower. I cannot get this thing to tune properly or run out. It has LOADS of compression, the muffler screen is clean, and the carb is in good order. I can get it to idle all day long, but it is horrendously rich on top (at factory carb setting.) If I lean it out, it will run somewhat better on top, but not idle at all. There is significant air coming BACK through the strato port when I try to rev it up. This does not seem normal to me. The blower has never been apart, and has been in landscape service for its life. Infrequent filter service, as is the norm for landscapers. Piston is a little noisy, but better than most used pieces. Any ideas?
