MCW
Somebody's talking crap here & it ain't the tree!
I am pretty sure MCW has stated the saw in his comparison, the husky one, was ported. Chain difference in both kerf and energy to get and keep going around surely would effect things. Thanks for finding all the data, I gave up looking for the stihl 241 fuel volume, stock to stock from the numbers, well look and see what you think.
No the Husky was dead stock. It has had a muffler mod since then though.
