Husqvarna 120 Mark II cuts with muffler Mod.  

Sounds alot healthier

frrom new zealand im an ex logger gr8 wee saw but we have the same issues with the 120 mk11 here also . seems the key thing is to get muffler to breath better seems to make a huge difference then re tweak carb. i shall be opening the muffler up on mine

i cant even use my saw for 10 minutes

Could you just run it without the exhaust deflector?

I got same 120 after 2 cuts it dies out on me

What size Bar and chain is that.

Eu tenho uma husqvarna vou fazer o mesmo 😅
