Anyone try the aftermarket Nikasil Echo 590 cylinder yet? Only one I have seen is sold by Saw Salvage. Looks like it may be an affordable alternative to OEM.

have you tried cleaning up your old cylinder or is it badly scored i just do it the way Mastermind does it- fast and does a good job and no acid
Can you even buy that am cylinder yet?
It was a pre order the last time I was on their site.
With any luck they copied the 620 cylinder so it's an upgrade.

Nah, going to start over. Yes it is for sale at Dukes.
By some miracle I have never been asked to rebuild an Echo CS-590 top end. Somehow they survive being beaten to death by tree service companies. I have serviced several and that includes those with the chain brake handle broken off. Somehow the top ends have remained intact and the engines remain good to go. These saws have been the typical replacement for the Stihl Farm Boss in this neck of the woods.
I got it cheap.It was straight-gassed. Put a LRB piston in it. Never was able to get the numerous flaws out of the cylinder. I damaged the piston again, mainly from a base gasket leak. It runs, I just don't want to grenade it as the rest of the saw is good.
Why bother with aftermarket? The OEM 590 and 620 top ends are quite reasonably priced IMO.
I might. Wanted to see if anyone had opinions on the aftermarket one.
My opinion is to go OEM. I've never once even tried an aftermarket P/C and never will. Decades of doing this for a living has taught me to stick with factory parts if and when I can get them, or rebuild factory parts if/when I can get the parts. When that fails I've been able to source out lightly used OEM but never even looked at going to offshore crap.
The vast majority of the work I did on small power equipment was fuel related, carbs fuel lines, etc. On two occasions I ended up with a cheap aftermarket carburetor not by my choosing of course, and both times it was a complete DISASTER. That's a 100 percent failure rate if my math is correct. I've seen quite a few aftermarket P/C's over the years and the quality it just OK to PATHETIC. Since OEM is top shelf, the decision is pretty easy from where I'm sitting.
Not directly related to your CS-590 but a few years ago I purchased a well advertised and less expensive bar and chain for my CS-590. I put it in service and on the very first outing the roller nose locked up so tight I couldn't get it to budge no matter how many different things I tried. The supplier replaced it and the second one has been in service a couple of years now, but as you can see from the pics has very little time on it.
OK, so what's the point. Right to start with the aftermarket bar REQUIRED a .058" gauge chain even though its supposed to be .050" which was WAY too loose and cut poorly. Second, yesterday the oil hole got plugged noodling some big wood into smaller pieces so I found pretty excessive wear when it was removed to clean it up. Yep, the bar is self destructing in two places. I have Windsor bars in service now since the 1970's that still look pretty good and have at least a zillion hours on them.
So is saving a couple of dollars on parts for these saws worth it in the long haul?........
