Has anyone had any engine trouble with their BR600's?

I had one go down yesterday. It was 1.5 years old and the mechanic said it "dropped a valve". He said it wasn't worth fixing. Then he called back shortly thereafter and said that stihl was going to put a new engine in it for free due to the problems they were having with the the 4 mix machines.

To make a long story short. If you have problems in the future make sure you have you're dealer contact tech support and you may be able to get the unit fixed for free even if it is out of warranty.

I probably have about $5 grand worth of 4 mix handhelds and it's been my experience that they are borderline junk. I can't count how many times I've had issues with these units. If it wasn't for the dealer, Stihl and I would have parted ways a long time ago.

i have a br600 since february and love it. i havent had any problems with it (yet). i also have a hedge trimmer and pole saw all with 4 mix engines. i love all of those pieces of equipment but i dont trust the quality of the trimmers. i had an FS100 for a month before it crapped out on me. it'll be a while before i buy another 4 mix trimmer cuz IMO they are junk. the limitations are too strict to run them... run with the guard on, dont run long string, have an EXACT fuel mix, adjust valves when servicing the unit... etc. much more trouble than a simple 2 cycle unit. as far as the blowers... yea they were having trouble with the 600's blowin up and Stihl was doing a LOT of engine replacements. now they have the Ultra synthetic oil to put in them so this type of thing doesnt happen.... but i was using the ultra when my FS100 went to crap.

Had my FS100 for 3yrs and had problem after problem with it. Earlier this summer it was in the shop and needed about $180.00 of work done and they were going to get it covered by sthil. The sthil rep happened to show up when I went to pick it up and the trimmer was still not running great. I talked with the 2 sthil reps about all of my problems and ended up leaving with a new FS100 for $100.00. The new one has been great, but I have been running the Ultra Synthetic oil in this one, but that oil is too high $$. I think I am going to start going back and forth with the oil.

I can assure you that there has been nothing but the Stihl oil in my units. I buy it by the case and I have had countless problems. I've payed close attention to the units that I've had the most problems with and it's the ones that are being used for prolonged periods of time without breaks. I've had virtually no trouble out of the 4-mix units that run on smaller properties except for coils. It's the ones that are on the large apartment complexes that may go all day with little break that just don't last.

The 4 mix units are probably great for the residential cutter or part-timer who doesn't rack up a lot of hours on the machines. They are junk when you put them on the large commercial properties day in and day out.

This is the kind of information I was looking for.......I was almost ready to try one BR600 this fall.....think I will go back to Echo I have used the 420...On a side note do you run and Stihl Trimmers that are doing well? Last good ones I run were 8 years ago....I was thinking about trying the FS80 since it is the only one with old 2 stoke enting I think?

Hmm, I am basically a homeowner who uses trimmers and blowers on my property and my rental properties so the long hour usage isn't there like you guys but this yr I bought a new Stihl FS100 and a BR600 and absolutely love the 4mix technology. I looked at Shindaiwa but they could be subbed in the worlds strongest men competition. Heavy as lead! I'll stick w/Stihl 4Mix. You're right on the synthetic oil too. Its great stuff and I even run it in my Husqvarna XP chain saws.

Using premium gas like what the owner's manual recommends could make a difference too. That's what I use in all my Stihl power tools and I have no engine issues or any others for that matter

Hess,

I do have some two stroke Stihl and I've had no problems out of these machines.

I would also like to say that I am one of Stihl's biggest fans when it comes to power to weight ratio on there handhelds. That being said, I am also one of their biggest critics when it comes to dependability.

I don't know how much clearer I can be by saying that I use the correct oil and gas. Bottom line is I've still had problems.

Onemantwomowers, you've got 3 Stihl units and 2 are what I consider homeowner models. Thanks for your advice but I've already made it clear that I don't have as many problems with the equipment if it is used on a lighter duty scale. I'm also assuming by your equipment that your using it on small properties where hours of straight use isn't a factor.

I will also say this, I'm not the one who uses this equipment. It's stictly used by employees so I'm not naive enough to think that they don't abuse it more than an owner/operator per say.

I'm also know that Stihl is very aware of certain issues regarding the 4 mix units and they have done quite a bit to correct the coil and engine problems.

Do I think they made the right decision by going to the "4 mix"? Probably not, but what do I know I'm just the sucker who got stuck with a lot of their unreliable equipment.

Any opinion on the FS80 trimmer..?

jcthorne-
you are correct but I will add that some days are significantly rougher than others and most of my equipment is not new in any sense, whatever that's worth. I've seen other posts on here where everybody was in love with their 4-mix trimmers, maybe they're all light duty users?

I do not own a BR 600 blower, with the exception of three Redmax and three echo blower's along with several Echo hedge trimmers, my hand held are stihl 4-mix (stick edgers, extended hedge trimmer's, line trimmers, quite a few dollars invested with Stihl myself) Some have been in service from the 2004 season, and have 1000's of hard hours on them. Powerful and fuel friendly, the 4-mix hand held has been a stolid machine for me. A couple of coil problems replaced under warranty, that's the extent of my 4-mix problems.I use Amsoil mixed at 80 to 1 or the Stihl premium oil .
