Any update on your findings?
No further update as of yet. I will be out cutting both Saturday and Sunday this coming weekend so I’ll know a little more and be able to update then.
I do have another question though that I’ll throw out here.
My other saw is an EFCO 152 with a 20”bar. I use an Oregon H78 chain on that. The CS 590 calls for a D70 chain. My question is why the different drive link count? They are both 3/8, .050 chains.

I live in Southwest Michigan. If anyone is nearby Kalamazoo area I'd be grateful for a little help.
Good catch. The 78 dl should have jumped out at me. I was still on the 20” 70dl Echo verses the 20” 72dl for everybody else page.Hi Travis, I know you stated that they are both 3/8 pitch but I believe your saws are not both 3/8 pitch. Your Efco takes a .325 chain, .50 gauge and 78 DL. The Echo 590 takes a larger chain of 3/8 chain, .50 gauge and 70 DL.
Technically Dahmer, yes it is bar shape, LOL. One bar is shaped for .325 chain the other shaped to utilizes a 3/8 chain, so I guess you could say different shape but the end sprocket roller nose configuration is what is different one roller nose is for 5/16 chain (.325) and the other is for 3/8 chain (.375).

Ken, you are correct. The Efco is .325Hi Travis, I know you stated that they are both 3/8 pitch but I believe your saws are not both 3/8 pitch. Your Efco takes a .325 chain, .50 gauge and 78 DL. The Echo 590 takes a larger chain of 3/8 chain, .50 gauge and 70 DL.
