Chainsaw Repair

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

Look in your Gmail

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,

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.
