Stihl 170
By: ChipsAhoy Date: October 3, 2017, 9:20 pm
---------------------------------------------------------
Hi, I've got one of these -new in 05- that was running good
until lately. It now wants to bog some when going from idle to
full throttle. It seems like it needs a carb adjustment but I
don't believe there is one other then idle. I've always used
E-free gas & sea-foam along with Stihl or Husky oil. It don't
have a whole lot of run time considering it's from 05, so I'm
not sure what kind of tweak it takes to clear it's throat.
Any suggestions?

Open the L side up some counterclockwise. Check make sure you
dont have the epa stops on it. If so pull. It is prob missing
the H side but should have I and L. L has to do with that
trigger response.
Carb diaphragm might be getting stiff but try opening the L
first.
New oem carbs with L and H like $25 new so weigh decision f it
ends up needing carb lit.

Saw is 12 years old and I don't care if you have always used
non-E gas, it is time to change the fuel line and filter. My
MS210 needs a fuel line just about every season even using Stihl
parts.

Thanks for the info. I used it awhile today and it seems to be
running rich.....oily muffler. Also used my 211 - same fuel- and
it burned clean. I'll try what you guys suggested and put a new
plug in also.

Oem Carb was likely single needle. They run good and well -
balanced when as new.

I've done the redneck echo fuel line trick in alot of different
saws. Stihls mainly the 025 290-390. But this is first 170 I
tried it in. Perfect. No more oem lines that just give up ghost.
Never cared for the molded lines in their whole older plastic
series myself.
Stihl 170. Guy never ran ethonal fuels. He always efree and also
can fuels too. Stihl 390 025 170 and now 261 replaced 025. The
390 025 has been redone over the years too. Till 025 last fix
was more then saws worth.
Never had one come back needing fuel lines after doing them with
echo line to date.
Cool thing about this guy. He cleans his saws up before dropping
off. All his saws always look like new. Just firewood cutter in
late 70's.
