'15 Echo CS620PW Information

What happened to it. Looks like it lead a tuff life.

Got hot and lots the piston then sat in a box for a few cough years cough... but it’s cleaned up good so far new piston and some grinding sans base gasket should be good to go.

Anyone have a muffler for sale?

My echo dealer just closed and cleaned out the shop. Was a burned up 590 in there but gone.
I did rescue this though.

I was gonna say BG delete raise exhaust twice the thickness of bg and widen both and see what it does.

Plug the decomp to gain a little more compression. It's not needed IMO. Squish on my saw was .014 Del took .006 off the edge of the piston and said run it. Still only use the decomp on first cold start.

I’m not a fan of decomps unless they are NEEDED... just another thing to leak air.

Removed one of the washers on the plug and got it seated nice and tight hope with the new piston it’s around .015 squish if not we will cut it.

My saw wouldn't touch standard sauder with the base gasket deleted. The stock squish should have it own area code.

Wow that wild... most Echo base gaskets I’ve seen are .015 to .022 think but thats just from the ones I’ve seen. May try some different numbers on this one.

Ok some updated got the saw completely stripped and cleaned, found TDC and when I get a ring going to map out the cyl.

Gonna go cut some wood!

 

[James Miller]

Did a little of that today. Yellow wood is good wood.

Did most of the cutting with the 600... need to grind some serious chains now that Oak was tough stuff!
