What chain?

[bkvanbek]

I bought a new Oregon 20" bar .325-78 DK .050 gauge. The bar says Poulan PRO on it but my saw is an Echo CS-520.

So will any 20" chain with a .325 pitch and 78 links, .050 gauge, work?

Do non-anti kickback chains cut better?

Yes and yes i do believe.

You will need to get a 20" chain that is the right number of drive links for your saw. I think anti kickback (safety chains) cut slower. If you want something to really rip thru thr wood you should invest in a full chisel chain with a square ground corner. Any chisel chain will cut better than a safety chain.

And those are the same specs as my saw. But can I vary at all from the saw specs, say like number of links?

Not for your 520. As you said it takes 78dl, .050 gauge .325 pitch.

Don't worry that Poulan and the Echo use the same bar mount.

Any chain with the same specs. should work fine.

Anti kickback chains do cut slower.

I recommend the 2 chisel .325 chains from Oregon. 20 LP[fastest and still safety chain] or if you want a little more anti-kickback protection then try 33SL which will cut almost right up there with the 20LP. The only non safety chains sold today in the 2 most poplar brands are the Oregon 20 LP .404 and the Stihl RSLK 3/8.
