Ok guys, so I know that there are a lot of threads out there about this piece of junk 359 but I have tried some of the fixes with no luck. I tore the saw all apart and checked piston and cylinder looks like new, compression at 140psi. I ordered all new intake bellows and etc. new zama carb and gaskets for carb and cylinder. Once I fired the saw back up I cannot get the new carb to idle at all. I messed with all the adjustment screws besides H screw. If I can get it to idle it will just die when i hit the throttle. Any adjustment past there will kill the saw or just idle really high with the chain spinning then bog with throttle. I decided to throw the old walbro carb back in and it fires up and idles no problem however as soon as it gets warm again it will not stay running like most other 359. Any suggestions would be helpful, thanks!
