Totally agree. More cleaning and it should be good to go.
How much compression do you think it will have with that much scoring? What kind of loss do you think?10 lbs 20?

After you run it for a while and areas fill with carbon, not much, if any.

My mind has been changed on what's acceptable, what's not, and what I'll shrug my shoulders and throw together. I'm still almost always surprised.

I'm willing to put another hour or so into it... then just hope for the best!

You might as well do it right. You've come this far...

I'm trying not to obsess about the cylinder too much, considering that I've never taken a saw apart this far, I feel like I've got Mt. Everest ahead of me with getting it all together again. Bearings, seals, piston, Motoseal is on the way from eBay... going to be learning by doing! I'll be over the moon if this thing runs again, but the promise of a "like new" saw has me pushing myself. If I fail, there's always Santa, he can bring me a shiny new orange saw.

You can do it. The fact that you've dove in this far is a big part of the battle. Take your time. I just got all of the parts in and everything cleaned and ready to assemble a 350 Husqvarna tonight. The assembly is a lot easier than you think. Parts seem to go together logically. By next summer you'll be bugging 12 local dealers for their parts units.

thanks man! I'm sure I'll be back with a post of a random part asking "where does this go!?", but this seems like the right crowd to help get me through this.

Anyone else ever use scotch brite? We get it by the roll at work. I use the grey (medium) then red (fine). It's worked well for me.

Update, saw is rebuilt and ran today! Well, without the bar, since I needed a new stud and accidentally ordered a short one instead of the long.
Sealed it with Motoseal and then waited the longest 24 hours, crossed my fingers and it popped on 3rd pull.
The worst parts for me were reassembling the chain brake (that damn spring!) and compressing the piston rings. Both could have been alleviated by having the right tool, but live and learn.
Overall a really rewarding process. I’ve learned so much by reading through this forum. Before I started this project, furthest I’ve gone with a chainsaw was sharpening the chain. Now I feel like I’m ready for just about any problem this saw could have for the rest of it’s operating life. Feels good! Had some fun too... already thinking of finding a “broken” saw that needs TLC and making it live again!!

Careful that's how it starts. Before you know it you will have more saws than you can shake a stick at.
I would have hit it with a brand new 390 piston and cylinder...
