    20190330_175005.jpg Got a little more 590 action when I got home from the mulberry haul. Big apple in the back yard. Got the 7910 ready just in case but wasn't needed.

    Ok new piston on, no base gasket sitting at .034” squish.

    116 ext
    132 Tran
    78 int

    Gonna take off .016” and see where that lands in numbers wise.

    Told you the squish would be wide even with the gasket out. Joe @Red97 might be willing to help you with numbers to shoot for.

    Was just looking back threw my PMs with deaves and he took .020 off mine and ended up at .014. So .016 should get you close to what you want. No squish band mods on mine.

    20190623_172426.jpg A little ported 590 love. The 355t isn't stock either. Standing dead locust score. 20190623_190115.jpg Must have been standing there a long time. That's the middle of the trunk

    Got the base cut by Rattler and is it sitting in pieces ready to port. I haven’t made up my mind yet or had time to mess with it but I’ll update when I do. Did get a full wrap on the 600P and it’s cutting like a champ!

    Good old 600P (muffler mod and tune/CS620 wrap and 20” bar) and the new dual port for the 590 in the works... should breathe well!

    Some day I'll drop the coin for the full wrap for the 590.

    Is that an aluminum rod sticking up in the 590 muff pic?

    Hey so I cracked my rear handle vibe mount on my 620p. So I was going about taking it off and the damn handle is not coming off the case. How does this thing come off to replace it. I went and bout the full wrap for the saw too. Figured might as well.
