Well, the 981 is a true 5 cube class saw - 80.7cc. It is hard to compare saws when their displacements vary almost 10cc. I mean, unless the bigger saw is clapped out, it will always come out ahead with power in the cut. The closest match to the 981 would be the 7900 Dolmar, but I don't have one to run against the 981, and I don't know anyone within a days drive of me that runs one.
Stihl 460 = 76.5cc, 4.5kW
Dolmar 7900 = 79cc, 4.5kW
Efco 981 = 80.7cc, 4.2kW
Husky 385 = 85cc, 4.6kW
Stihl 650 = 84.9cc, 4.8kW
As we know, specs only tell 1/2 the story - everyone lies about power output, weight, etc. Troll will tell me the saw is a boat anchor because it doesn't look too good on paper. I like torque - I like running odd-ball saws that aren't really popular - I am only cutting firewood.
First impressions - I like the air filtration. BIG fuel/oil tanks (30oz./15 oz.) Very stout sidecover and double spikes. Excellent, nonrestrictive muffler - very easy to modify. Nice, straight top handle (personal preference). Nice fit and finish - everything lines up. Built like a brick chithouse! Somewhat cheesey on/off switch and choke lever. So/so throttle lock.
This saw will wear a 28" and 36" bar - the bar in the photo is a 36", Full Skip chain. Forest service permits aren't ready yet...so I am patiently waiting to get out and cut.
Oh, she tips the scales at 15lbs 3oz. PHO.
