A few days ago I bought a new Stihl BG86 blower. The "tech" says he's going to service it in back. I said, "What does "service it" mean?" He says "Gas and oil it, then adjust it and make sure it's running right." He then comes out and takes me back to teach me how to start it. It didn't seem to run right, as it was bogging down a bit and not having near full power. He says it's the newer style muffler. Next day I take it to the job and again, acts the same like it's bogging down and no power. I take it back to have them adjust the carb.

Now I'm getting some personal attention here and figure they'll do it right. Long story short, they didn't. I went to the job sight and again, acting exactly the same. Upon returning they agreed it's not feeling or sounding right with lack of power. They offer me a brand new one to replace, so I returned the 1st one for the 2nd one.(no spark arrestor problems) Again, I was apprehensive because although the 2nd one was "sounding" right, it appeared to lack power, but more than the first. I go to the job and AGAIN it does the same thing as the first. Take it back and now they can't get it adjusted properly. The manager can tell by listening, as we all can, that the blower is not acting right. I had option of getting a 3rd one or money back. I opted for the money back.

Wtf(fudge!) is going on here guys? They even had one mechanic I knew he knew what he was doing. I could just tell. He got the 2nd one adjusted right in the shop, while it appeared, but got in the field and notta. For the adjustment they just worked with the H & L carb settings.

Anyone else experience this with a new bg86 blower? How about used? What do you think the problem could have been?

Thanks.

I was thinking of getting blower #3, then thought it will do the same thing. I told the manager my first troubleshoot before any work is done checking the 2 blowers, was to check the gas they're using. 2 new blowers, 2 not working right. Something wrong there for sure.

Purchased a new Stihl SH-86 blower, shredder, vac in May 2009. Retuned the carb with a tach after a few tanks of gas. When I richened up the carb, I didn't even hit the limiter stops on the carb adjustment screws. Starts in 1-4 pulls and runs like new. Lots of power for a hand held blower. Not a shred of trouble with it.

Really well every piece of Stihl I have ever purchased they just added gas and lubrication if needed to a saw then the dealer fired the item right up, they have never had to adjust on any carb at the dealership to get anything of mine to run correctly.
I purchased the BG86 replacing the BG55 last year and it is the most used Stihl item I own. I use it numerous times weekly to keep my porch and carport blown off, not to mention when mowing season is here blowing off my mower, around everything, etc etc etc.
Now I do use 93 octane gas with Stihl HP Ultra mix only for all my Stihl items.

I have many stihl chainsaws and other power tools they make. I love every one of them except for the bg86. The thing just won't wind up like it should.

This thread makes me glad I bought a Husky blower. I didn't spring for the vac option though. I couldn't see myself using it.

On topic: I wonder why the 86 doesn't run right?
Zama chinese carb.its just a complete piece of sh.........junk! Got 2 one for a blower and one for a vac but have an extra vac kit.close to $600 wasted.rebuilt one carb to begin with and took it back under warranty.2 days later they called and told me the spark screen was plugged in the muffler.$32 later and still had a boggy ass leaf blower.oh how i wish walbro made mexican replacement carbs.lol

When you say bogging, I think that the hi speed screw is to rich. Is the problem that you can't get it lean enough to run without bogging?

EDIT: I am guessing that the bogging is leading to an overall lack of power correct? What is a good test of leaf blower power? I used mine to move leaf piles that were almost as high as my knees and sometimes as wide as a couple of feet thick. IDK, maybe mine should have more power than that. This is my first gas blower but it is still more powerful than my electric blower was.
