Husqvarna 359 my tree service friend from the neighborhood brought me to look at. Did an ultrasonic carb clean before looking at anything else, then found it only had 80 psi was the problem. A look at the piston told me all I needed to know and pulled the jug. Initial thought was jug was too far gone to clean up, but am reluctant to buy a cheap Chinese cylinder and the Hyway kits are about 3 times the cost of the cheap crap kits, and the OEM about 6 times. Kinda depended whether he wanted to give me his dead 359 and some money for one of my nice running 455 Ranchers I want to get rid of, or he wanted me to fix it for him, cause I warned him he'd probably be in it for at least $200. No reply from him yet, so I had a second go with muriatic acid to clean the transfer and went at it with 600 grit. In the end I got it really nice below the exhaust port but for one tiny spot and a couple of scratches above the port. Not my ideal jug, but should work okay. Ordered a Meteor piston kit for it, so should be able to get it running decent for $40 in parts. If it's for him, he'll probably figure out how to fry it in short order again so no need to fix it up too nice, and if it's for me, I have a way lighter MS361 I rebuilt I'd use any day over it so I don't want to put much in it. I think it was probably an already abused pawn shop saw he picked up, but will check for seal leaks if I keep it for myself. Second pic is cleaned up cylinder. Don’t like that ugly big main scratch above the port but understand from seeing others with about the same scratch that people cleaned up, will just lose a little compression but should run fine.
