Need advice with rebuild 070

[Sheep_wrangler]

So today I was milling up some spalted maple with my 070 and 36” bar and I noticed it lost most of its power on the last cut. Feels like the piston and rings are going... I’ve got a 070 that may be a franken saw with Chinese parts sprinkled in but it’s been running like a champ up until today. I’ve had parts replaced and I think it’s time to do the piston and cylinder. What aftermarket parts should I go with? What should I replace besides the cylinder and piston. I’m also considering upgrading to an 090 rebuild or if I can find one I may just replace the saw.

You could probably get an OEM cylinder kit, or buy a whole one new, and keep the old for parts. See the link below.

Your link is to a thread that is close to 7 years old so it should be ,dis regarded by those reading this thread.

If it was me I would order two Farmertech and move on. That is what I did. I could not be more pleased with the out come. I do not want to hear the Chinese BS. I would buy from Stihl if they made old technology stuff. I have learned a lot about how to make the stuff last. I use Loctite most every where and go cut. I also keep plenty of spare every thing on hand. I would venture the saw did not wear out It was improperly used. Let me add there there is no OP here or any where that the OP does not error some times. Thanks

The thread listed above is alive and well. Robin Wood has an MS720 right now. Same as an 070 from what I can tell. $1600 shipped to the USA.
