ms170 ws manual

Hi Guys,
I could really use the above ws manual as the 017 ws manual that
I have just isn't quite there. Few differences, specially the
snorkel carburetor. This carb seems to have both H&L fixed and
only an extra air adjustment (which has a left hand thread??!)
So is this a type of "Stratos" carb?
Many thanks in advance
Lee

No, the snorkel goes to the air cleaner and is supposed to help
when the saw is running a dirty/clogged air filter.

Hey thanks Fish,
My snorkel carb gets its air from the same place as the normal
venturi, ie both have to pass through the air filter. I think
there must be another reason for the snorkel. I think it may be
similar to the Poulan Stratos engines. Anyway I don't like not
being able to adjust the fuel mix. The only adjustment is to
increase the air flow which only affects the idle, which oddly
enough has a lefthand thread!
This unit has a scored piston which I think was caused by the
mix being too lean, as per the EPA requirements. I'm thinking
of putting on the adjustable carb that was fitted to the earlier
model of the ms170.
Regards,
Lee

No, nothing at all like the stratified carb. The air coming
from the filter box is pretty much the point. Here is a tech
bulletin
from the 029 snorkel carb/same setup.

Like Fish stated....far cry from a strato carb.
The snorkel like vent is what STIHL calls INTELLICARB.
And its function is once again.....just like Fish stated.

Thanks guys for putting me straight on that issue. I think I
would still like to replace the carb with a fully adjustable
one. Do you see any problems with that solution. The earlier
170 had a normal carb i believe.

I had a like new 025 with a single needle carb. Actually the
mixture was "OK" but I didn't like the idea of a single needle
carb.
The new carb was less than $25 from the Stihl dealer. Was a bolt
in change over. Now I'm content.
