Your piston is trash. What your cleaning out of the cylinder is your piston! Meteor pistons are $40 and oem are just a little bit more.
If I can clean up my original cylinder "by hand with 150, 320 emery cloth and red scotch brite pad and then with a dremel", is there any reason that I could not similarly clean up the original piston and reuse it with some new rings?

I would never run 50:1 regardless of what the manufacturer says!
I found an 026 parts manual and I've been working on the PNs I will need to buy for the overhaul. My SN is 134976153 so it looks like I will need the short fuel hose. My Walbro carburetor has 2 adjustment screws on the side and is stamped WT 194 C6.
Some questions:
- For the clutch bearing, I see there are 2 PNs: 9512 003 2260 (CDN) & 9512 933 2260. What's the difference?
- Does the Stihl piston kit (1121 030 2001) include the snap rings (9463 650 1000)? They're not listed but they appear in a catalog photo.
- The wrist pin bearing (9512 003 2250) does not appear to be included in the piston kit. Am I correct?
- Presumably, the WT-426 compensator carb compensates for a plugged-up air filter. Would I need a different air filter and add a compensator hose?

Run a good quality oil, e-free gas and you should be fine.
I got the cylinder off and, to my untrained eye, it doesn't look too bad. The exhaust side of the piston is scuffed and the rings are flush with the skirt. The rod doesn't appear to have any play on the crankshaft. Any guesses as to what would cause this sort of wear?
I see that Tecomec is an Italian company. Someone here recommended that I also look at SawParts Canada for parts and they appear to sell Hyway, which is a Taiwanese company. Weedeaterman lists its 026 Top End Kit for US$145.99 (~ C$189.79) while SawParts Canada lists its Nikasil 026 Top End Kit for C$89.99. Is the Tecomec top end kit really C$100 better than the Hyway?
I emailed some parts suppliers for rebuild pricing and they have been very slow to respond. So far, just my local Stihl dealer (Lapp Cycle)and SawParts Canada have replied. I'm waiting to hear from Niagara Saw as I stopped in earlier this week to follow-up on my quote and they wanted to know if I have a thick or thin cylinder gasket. I've been busy lately on cutting more ash to focus on fixing my saw.
To answer my earlier post, I see from pure-gas.org, I can get ethanol-free 91-octane gas at Shell, Esso, Canadian Tire, Costo, and Ultramar. Delta Sonic sells e-free gas in Cheekotowaga, NY. Luckily, there's a Canadian Tire and Shell in Fort Erie in case I don't feel like going over the river.
I'm going to clean up my old cylinder and use a new piston. I haven't decided which one to buy yet.That piston is crap. Throw it out.
I realized as I was taking it apart that I probably should have cleaned it off first. I don't think any sawdust got into the crankcase so I was thinking that I could put it back together, clean it off, and then disassemble it again for the rebuild.You really shoulda blown off that saw good before disassembly. It's gonna be a bear to keep stuff out of the crankcase during reassembly. I've been there too bud, in a rush to see what's up. Gotta clean before hand. ... I'd stuff paper towel in that crankcase, tape the rod up with some masking tape, and clean that saw off before you do anything else.
Huztl?If you're deciding Huztl, eBay is cheaper than what you're stating. You need to measure your cylinder to confirm its a 44mm and not a 44.7mm. There's a seller on eBay that's got OEM 44.7 piston with rings for $25 shipped.
Agreed. I have done this now on two occasions with 024 OEM Mahle cylinders and they hone up very nicely. After installing the new piston and rings, I generally reach 150 psi. compression with the old, honed cylinder. And, the engine starts and runs strong, of course.Try cleaning that oem jug up. They are, generally speaking, better than aftermarket cylinders.
