Trust me, that saw has balls. It's an 85cc Dolkita Big Bore. It just seems weak because it's running dull full-comp on a 32" bar completely buried in hard white oak and I was making the mistake of (subconsciously) compensating for the inadequately-prepared chain by forcing it too hard.
Not meaning to Monday-morning quarterback, or pick, but no matter how much it has in the way of "balls" it falls short in the brains dept. with dull/insufficient-joint chain. Especially approaching such a tree.
Whichever side of the chain is the dullest will generally wear down the bar rail on that side, too. :msp_sad:
It is a CHAIN-saw after all. Just glad to see you got it down without incident. Go file that chain.
