Husqvarna 346xp NE piston problem

[Georgi Ivanov]

I have 346 buy it in 2015 brand new, used few times (6-7tanks),saw is last started in 2017,i get dessision to maintain it, because it sit like this for long time.. Carb set, fuel line, filters... Then I remove exhaust to chek and is appear to have way too much deposit for just few tanks... Oil i use back then was Husqvarna XP 50:1...then I find piston actually meet the intake wall, and i I disassembled the entire saw, full inspection of everything, crankshaft, bearings, bearing beds in the crankcase... Everything is perfect... I already change bearings and seals... Cylinder is in almost new condition, no scratches, nothing... Friend of mine who work on jdm tuning messure cylinder and plate in it... Everything is OK... And still piston touch it somehow...
What I should check more? Did someone face that? I am really curious what caused this or just saw is defekt somehow from factory?
I am into dessision to buy new OEM Mahle kit, because I can't find just OEM piston or to buy only Meteor piston and ring... I am open to advice

And still piston touch it somehow...

Touches what?

 

[Georgi Ivanov]

Touches what?

A cylinder wall... On piston bottom

there is no problem. This is a normal sign of use.

So is normal to look like this?

 

[Woodwater]

yes.

 

[jacktheripper]

Clean it with solvent and a brush. Then stop running sh*t oil

Agree. Probably looked like that after 1 tank and will still look just like that after 100 more tanks.

As the others have told you, that piston will work fine. We use a phrase over here "Send it" It means you are good to use what you have...

Looks good, run 40:1, ideally grab a better oil. The XP seems to protect well, but when I tried it, I ended up with carbon everywhere. I ran about 4 gallons through my 562XPG and the whole top was carbony, even under the rings. Switched that saw over to Red Armor and after half a tank it was already cleaner.

That's fine. Get some red armor or dominator oil and run it at 40:1.

In Bulgaria is really hard to find Red Armour... I get Motul 800...

If you can get Motul 710, it will work better yet in a saw and burn cleaner
