Yep has turned into a rebuild. Think he was hoping for a simple fix.....aye well have a chat about filter cleaning.....the rest if the saw isn't that dirty in fairness...do they do a hd filter for 550 of any decent mods? There is no sign of any hole or split in the filter at all but inside was dirty with very fine dust.

Look forward to hearing of the 110 rebuild

My understanding of this prob with fine dust is people not using a airline when cleaning filter 🤔 is this correct

As far as I am aware Bill, the Husqvarna saws have a centrefuge airflow off the cooling fan / flywheel which is 'supposed' to spin out larger debris - so yr filter lasts longer between cleaning . K

I always wipe a thin film of grease around my filters before seating them, it seems to cut out all of that fine dust finding a way into the carb.

Fit the orange frame filter 25 micron

I'm not on here much, and just had a catch up,.  Umm so it was compression,  and bad air filtration, by the looks of that piston, it's been going on for some time. 

I would also pay attention to the big end and maybe the crank. I'd try and flush it a few times, and also filter what comes out so you can see what is collected , and see if there's any play. First and also check afterwards.

 

its your rebuild, it's upto you  what's good and what's not really good enough

 

cheers

Piston ring fitted, saw back together and seems to be running sweet. Havent given it a good run as no bar and chain but revs and idles fine. What a bar stuart that carb is to fit back in, fiddly!
