What model Stihl? Actually Roger, I believe the Partner/HVA saws have a poor filtration system design compared to Stihl. Almost every one I see has some sort of C/P scoring. The other thing is that the users NEVER seem to use the built in water spray when cutting, perhaps the use of the water which is designed to keep the dust down would contribute to the longevity of the saw by sort of helping the filter system out? Rarely do I see a Stihl with scoring unless it is raw gas related.

Sounds odd - as until recently it was the other way around with chainsaws.

However, we are of course talking about a totally different kind of dust with cutoff saws, so it could well be true anyway.

The Stihls were 2 TS 400 one TS 420 and a TS 510.   The 510 was a big heavy saw with a 12" diamond blade on it.   When I revved that thing up it was like hanging onto a large gyroscope.
 The scoring I found in the Huskys was severe and had to be caused by a lean condition or straight gas.    I did find a Husqvarna 970 I believe it was, where cement dust had worked into the throttle shaft of the carb and it started to wallow out causing an air leak.
  I agree with you on the water.   These things have so much cement dust in them it is a wonder they still worked at all.

I still haven't gotten into the Partner K700 that's been sitting on my shop floor for months.  It'll need a new P/C methinks............so I may just part it out on the bay. 

Would like to have a good runner cutoff saw of that size however.  I have a Target Q65-14 that's based on a McCulloch 795L.  At 103cc and somewhere around 30 pounds it's a beast.

I see that there's some aftermarket P/C sets out for the K700................but am skeptical of the quality.  For now I think it'll remain on the shop floor...

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

to remove the carb, with air filter removed there is a stud through plastic housing remove it, pop the throttle rod from trigger. lift up take off fuel pipe  that should be it be careful putting back to line up choke lever.
