EPA carbs

[alamo-kid]

thing's are getting worse



I just got back from the "Big Stihl dealer" in the next town he stocks and sells lots of smaller saws and landscape equipment. The bad news is that just as "165" has told us every new Stihl on the shelf has no high speed adjustment on the carb. a good friend of mine is the local Shindiawa dealer and we to looked at the new saws and the dealer updates and Shindiawa is also using these new "fixed high speed jet carbs". He has a pile of rental saws with scored cylinders because they have been run lean. He is going to try and order "adjustable barbs for these saws but is not sure if the old "adjustable part #'s will fly with shindiawa because of these new "EPA reg's". Evedently you can still order the old style carbs( with high speed adjustment) for the Stihl saws that have been changed over to fixed jet.

But, what happens when Stihl or whoever saw company introduces new models that never had "high speed adjustment carbs". Then what "we" deal scored cylinders or saws with poor performance "ie. run to rich"

What are we the consumer to do?????????????



buy "old saws"--"buy old Carbs"--"buy Canadian saws"

Or you can just come to Indiana where it is <b>emphatically</b> not the case of "every new saw has fixed jets".&nbsp; Heck, even the new MS 270/280 has three adjustment screws.

My new 440 has both screws and my 260 pro does now as well. I have heard fromn my dealer just the opposite. Stihl is going back to adjustable carbs. BTW I doubt the fixed jet has anything to do with emmisions. An adjustable jet carb can be run as lean as a fixed jet carb. I am betting they did it to keep the averge joe from leaning out his saw to the point of seizure.

Some of the Shindaiwa saws that I own have fixed jet carbs. The 488 I changed to the older fully adj. style. The 360 model on the other hand doesn't need it. It runs at 13'500 to 14'000 rpm. The plug is burning the right color and the saw has ball$ to spare. I also run Maxim K2 at 32:1.

I am not sure about Stihl but the Shindiawa "dealer service manuals clearly call the new carbs "EPA" so let's hope there is a change back to a real carb

Shindaiwas are a strange breed. The New 488 and 360 have a brass plug, no adj. screw at all. The 757 has a limiter cap on the low adj. and a solid plug on the hi adj. Pull both caps and full adj. screws are there. Go figure!

shindiawa 357

I want to order a 357 from my dealer but I also real want that"adjustment" but since is 200.00 cheaper than an Ms 200t that doesn't have a high speed adjustment either so for 200.00 maybe I can buy an older carb.

guess I'll cross my fingers and hope it's NOS

My understanding is Stihl will return to fully adjustable with limiter cap carbs on all equipment. Of course they will use up any fixed jet carbs in stock before switching. Then dealers who don't move product very fast may have fixed jet product for some time so buyers who want adjustable product will need to check what's available at their dealer.

think bwalker is rite. id still like to know how many people on this forum have
leaned one out to the point of no return.
surely i aint the only one.i mean they sound so darn good, screaming like they do.i found out, why they wus screaming so loud tho, and it aint such a good thing.

EPA

Just because it has an EPA carb does not mean it has to run lean to the point of seizing. They can be adjusted and should be if they exceed the top speed in the specs. Any good dealer should know how to do this.

Unfortunately, it is obvious that many here do not have a good dealer available. I have a fairly good dealer that is well stocked and usually has what I need. But I cannot afford his service department since I have never seen a single piece of equipment get out of there for less than $100. The owner also told me that the fixed jet carbs were not adjustable and I would need to buy a new carb. He was probably just pissed because I bought the saw elsewhere. Whatever the reason, I am in a position where I can no longer trust him for repairs.

My dealer is great. He gave a me a adjustable jet carb to fix the fixed jet POS. Turning a screw is much easier than than swapping jets. BTW Does anyone know the correct no load rpm for a 260.

I stuck my head in at the local shop today and looked at every Stihl saw.

Fixed jet models:<ul><li>170<li>180</ul>Three-screw models:<ul><li>210<li>250<li>270<li>280<li>310<li>390</ul>I take that back, I didn't look at the 290.

He also had an older 3-screw 066, but all the other saws are brand-spankin' new.
