    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?

    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.

    Photos in a minute.

    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.
