My BG 86 is now 5 years old it did the same thing more than once

Also;
-Bolts attaching head and crankcase became loose
-Carb return spring broke, not a service item!! The guy at the Sthil shop I have used for 25+years took me behind the counter to show me the parts he could order. Broken return spring=new carb at $100+. I ended up with an ebay carb for $28 delivered in two days that works fine but for how long?
-Clamp system holding nozzle on failed so is now held on with self tappers
- Muffler continually came loose, so very strong loctite applied to the bolts the last time it happened. To my utter disbelief the muffler came loose again this week. On inspection bolts still firmly loctited in place, they are never coming out but the muffler has broken away from the mounting.
Sorry
So I am in the market for a new blower, what do you guys recommend?
I have had several Sthil blowers but have been burned this time (let it go Work Horse)
I have had Echo blowers in the past and they went well.
