New member here and thanks for the info gleaned so far (great forum).

I'll try and condense my story as to how my BR600 got to where it is and get back with you later tonight with the rest of the story when I pick it up from the dealer.

The unit is probably 3 or so years old, always ran Stihl oil and has never not started or ran well besides the fact that it has lost some power over time (both with the old wand tip and newer style presently installed). Because I move snow with it this original out-of-the-box power was important to me and I ended up taking it to another dealer when my original shop insisted that it was up to specs (rpm-wise). After $250 worth of parts/labor (bad trigger, first valve adjustment and minor misc.) I was back to the pressure/volume that I remember yet not necessarily reliable initial start idling especially when it turned cold. I would basically have to grab on to the choke so that it didn't stall or tend to run away with itself when adjusted back...yet it warmed up quickly and didn't seem to be an issue. It never really sounded much different after the overhaul than what it ever did at full throttle when new...just performed a bit more noticeably which I was obviously happy with.

I was moving snow and water (more of the latter this freakishly warm year) like nobody's business for maybe 10 jobs until I went to start it the last time and...no compression. Took it to the dealer and no good news over the phone but something about "somebody's been into it before.." "hole in the cranckcase.." "$200 piston..." ....and basically a feeling of regret on my part that I ever screwed with getting more out of it in the first place (nobody had touched this machine besides rpm checks/adjustments before they adjusted the valves).
One thing I remember when buying this (and I'm not knocking the product) is that my serial number was not necessarily included in some big 'change' that Stihl made with these blower motors but that it was old enough to obviously not be included among those evidently grenading on a regular basis (which obviously was the case since it lasted this long on not a commercial use level but from seeing heavy home use being my favorite tool by far).

Is there anything that I should ask about in regards to what they saw in there when they had it apart? I'm halfway thinking about simply picking up another if you guys feel that this is still the best volume/pressure/per weight producing machine on the market today or that I will be happier with the next one (I don't like losing volume/pressure long term when blowing snow or dealing with what seems like a very cheaply made throttle/trigger assy. with plastic screw adjustment).

Back with more tonight and I sincerely appreciate your input as I always thought that this product would last me much longer after I got through the original "yeah, we improved that later..." initial scare.

Yes, Stihl has addressed issues with the BR600 engine. But why even mess with all that complexity, regular valve adjustments required etc? IMHO, don't buy another one. I went through this decision last spring and bought a Shindaiwa EB801. It's not only a simple 2-stroke, but it's more powerful and has a completely reliable track record.

What's a br600 and how much wood will it cut? Oh my bad, thought this was the chain saw forum.

Eh, I can understand why the OP posted here.

1-Most of us have blowers as well as chainsaws
2-Similar engine designs
3-Similar support/troubleshooting methods
4-There's no good site (that I know of) like AS for other small power equipment

I share the concern that we don't want this turning into a dumping ground for random equipment posts, though. So I can see where you're coming from. Tough issue.

I'll ask the mods to move this if that's appropriate...yet for some reason my search is coming up with all references to this widely used product in the chainsaw forum with (from what I can see) no previous debate otherwise. Do tree specialists 'rake' up what falls under the tree for their more discerning clients and then physically bend down/pick up/leave whatever's left behind...or do they use a blower?

Thanks for the help, blsnelling. I'm looking at the RedMax models obviously as well but have no idea who makes the better (highest volume/pressure/longest lasting) product which is all that I am interested in regardless of price.
 
We cut wood and haul it away in a pickup but don't post about those here (well not much anyway). This is you first post. YOUR FIRST POST! And it is on a chain saw forum and about a blower????????? :frown:
 
I've said it before and I'll say it again. There is no place for a cam and valves on a blower/trimmer/chainsaw, especially when the camshaft is made out of plastic like on the Stihl 4-mix motors. The 4-mix engines are the definition of CHEAP JUNK in my humble opinion.
 
Got that first cup of Joe on board and things are looking up. LOL

Been there myself more than once...:cheers:...I think the problem with you guys (and the manner in which you've obviously built up this forum)...is that when the rest of the world comes across engine related posts in here that are obviously from folks who know what in the heck they are talking about...good people are hard to find. :bowdown:

In the spirit of trying to give something back; here's what the dealer came up with as the root cause of my failure (in layman's terms):
If you can picture the square machined surface between the 'block' where the piston and valves reside and the other large square piece of aluminum that mates to it (crankcase?, I didn't check)...they are saying that they pressure tested this assembly before disassembly and found a leak that most likely caused a lean mixture/temps. to rise and the valve guide to get sucked down into the body causing bad things to happen obviously. What the kicker was in their opinion was that the two halves of the assembly were not gasketed but 'rv sealant' glued together...which would be somewhat impossible if this was not standard practice at the factory (I have never had it apart or worked on). I asked them to at least get the regional rep involved and tell me that this was standard practice...as the only time that at least 'I have ever used sealant was as a last resort on worn surfaces or bad castings and especially not where it could possibly weep in to an area where again bad things could happen via contamination.

I can accept this 'slow leak' theory (maybe why it never performed again as new over time) yet I told them also to give me an idea as to where my serial number sits in relation to where these engines have had problems in the past and what was done to fix them....which I was hoping someone would have insight to on here.

I'm not giving up on Stihl (yet); simply wanting to know whether this is a common occurence or not and whether catastrophic failure in this vein is usually the result (makes sense to me, but what do I know....).:confused:

A "clamshell" engine is always put together with a sealant. A gasket cannot be used. Yes, catastrophic failures of the BR600 are common, at least on older ones. I've torn a number of the down myself.

Thanks, I suppose that blows the "mystery sealant" and "somebody's been in there.." theory all to pieces.
My question now is how do you trust a Stihl design that has been 'improved' since then in other unrelated areas...when a simple air leak can grenade it anyways? (keeping in mind that I may just have gotten a dud).

Btw, in searching the forums I thought that you were in the market for a blower at one time but don't recognize a model number in your signature....did you come up with something or am I mistaken?

Brad, I have four (4) BR600's that get used H A R D for 9 months out of the year. During leaf season, they only stop to have fuel put in them. I have not experienced any failures, let alone catastrophic failures. Maybe I just got lucky or maybe it's the HP Ultra and 93 octane they get fed? Either way, I wouldn't hesitate to buy four more of 'em.

Before I converted all of my 2-stroke stuff to STIHL, I used RedMax exclusively and I have had way fewer problems with the STIHL equipment. I wouldn't be opposed to running Shindaiwa hand helds but I have no dealer support in this area.
 
The BR600's have been very durable since the improvements. I'm pretty sure the group of 600's Brad had were beat to death commercial junk. By the way they looked, its a testiment to their durability, as some or all were not updated with the improved engines. Stihl manned up and repaired them even if out of warranty.
