Thread: To those who like the Intellicarb...

My brand new Greffardized MS260 Pro tachs at 15,300 rpm within 2- 3 seconds of holding the throttle pegged with the bar and chain on. Is this OK? LOL. Initially Dennis was concerned that he wouldn`t be able to get it running lean enough as you normally have the HI speed screw open less on a modified saw than you would on the same saw stock since the LO speed screw is contributing more, doesn`t appear to be a problem here. When I first got it home it burbled normally at WOT and I didn`t bother to tach it, then after about a half tank of gas (5.5 minutes, Thanks Brian) it starts this. I gave it the obligatory spray down of the seals and held the saw in every possible position and didn`t find any evidence of air leakage, don`t feel like building a throat plate to vacuum and pressure test it so off to the shop it goes. Yeah man, this is way better than being able to tweak the hi speed screw! Russ

And just how is this MY fault??!!

Oh, I will have my 026 adjustable carb by Thursday (I hope) and will have a barely-used fixed jet IgnoramusCarb for sale, CHEAP! Do you want the .58 fixed jet out of it? Or are you going to do it smart and swap carbs BEFORE going through 6+ months of frustration?

Russ, I guess this just builds a better case for staying with Husky or Jonsered. Is this carburetor problem typical in all of the Stihl saws? Seems to be the MS260 is mentioned more often. Good luck with it!!!

I've run a couple new 260's and they ran fine. Seems like every bad carb is on the 260Pro models. Me, Ben Walker, Russ and others I'm sure.

So your saying that you had your saw modified, and you expect it to run with the same carb settings?

Not to mention what might have changed on the port timing, which could make the saw over rev...

Take a fourwheeler for example, you bore it, and do a head job or whatever, what do you do with the carb? You get bigger jets, or get a bigger carb.

If ya know about saws so much then why don't ya work on them yourself.


Well im off to the "shop"

Ya. My non-pro MS 260 doesn't have a bad carb.

All this stupid stuff that stihl is doing seems to be targeted at begginers. The non adjustsable carb......cuz most people do not know how to properly adjust a carb and tend to set it incorrectly. The "saftly" bars and chains, etc.

E-bay Item # 2306751100, only a little more than 3 hours to go.
NEW 028 carb orderd by mistake last yr. part# 1118 120 0601.
Currently at $16.25. Don't know if this will help you, I just ran across it, this morning.

Of course not. The only mods I made on my saw was to open the muffler so I could get the power that the saw SHOULD make, and reduce EPA mandated extra heat to extend the life of the saw. This usually requires a simple carb adjustment, which should be a 30 second procedure. Instead it is now a nightmare. But I guess pro users should all run clogged up saws with no power and safety chain and perhaps those bolt-on bar tip guards to prevent kickback?

Jim- Why are you defending the new smaller Stihl saws so heartily when you only run (older) 066's? You have no basis for your opinions. A saw that 'sounds' right in the shop may not PERFORM like it should in the field.

The 026 is a homeowner saw, the way I see it. It's too small for logging, firewood, or arborist work. It's too big for a climbing saw. Their may be some special applications for a saw this size, I don't know, maybe some bucket truck use, orchard prunning, or something.
Bwalker asked if it was a foo foo saw. I don't know about how it is put together, but for size, yes it's a foo foo size. Good for a young girl, old woman, or it could be a size saw that would suit a homeowner, someone with a few acre lot with trees, doing some occasional cutting.
These are the guys that futz with the screws and blow them up, so perhaps this is why stihl left them off.
As far as saw mods, sure the epa wants to discourage this. Otherwise every tom, ####, and brian are cuttting up the muffler.

Mike, aren't you getting an Echo 346 modified by Ken? I guess if YOU have a saw modified it doesn't count, huh? And what would you suggest for a climber with a weak shoulder to use for blocking down 12"-18" wood? Your suggestion that the 026 is a foo-foo saw for homeowners only is too asinine. Almost every tree crew I know has at least one 026. Should I lug up a 14 lb saw instead?

I would say an arborist with a bad shoulder is a special application. If it work for you great.
I carry an 026 pro around in the truck and just haven't found much of a use for it. We leave it near the chipper when chipping sometimes, if there is just one or two small cuts, it's easy to start, but for meat and potatoes cutting it has not been of any use.
As far as moding a saw, cool, but don't call all sthils junk because your mod is giving you trouble.

Oh, now I get it. Thanks, Mike Maas. The saws were what Stihl said they were, the owners modified them, and are now upset cause they don't run to expectation.
Now, if I want to modify my saw, I have to expect to install larger jets or drill the existing ones. Thanks Brian & Ben, Stihltech & JimL.

Mike there are a whole heck of a lot of people out there that don't know a 026 it too small for firewood, so don't go spreadin that around, you'll confuse them.

i have three stihls with the IntelCarb and haven't had any problems with any of them. When some thing is mass produced the odds of there being a few "bad apples" are pretty good.

I am not defending them, wouldn't own one of them lil buggers anyway. Just wanting to set it straight, and livin this place up a little more than the usual coments from the special people (gypo)

I can tell you this though, you opened up the muffler, I put a pipe on a kids fourwheeler, 99% of the time I have to put in a bigger jet. Usually 2 sizes bigger.
Same senerio...
