Echo, Stihl or SOLO chainsaw engines?

The warranty on a Stihl is 90 days for a cosumer and 30 for a pro.I used to do tree work and worked for a Stihl dealer.The power heads last forever but you only run them for a few minutes at a time.They are made to run at full throttle, 1350 rpm for the duration of the cut.Stihl claims x amont of hp but they don't state torque.****,try it.

SOLO's have been around for awhile and were used on ultralight aircraft, they get my vote.

If you can use a motor in an ultra lite then it has consistant torque and cooling.In a woods condition you only run the head for maybe a minute or two at a time and then shut it off and fire it again a moment later.I still have to wonder if you would wind up with a huge rear sprocket for torque.

Roadkill, I Am Going To Ebay And See What I Can Find For You, Hopefully A Super Deal. I Will Pm You.

personally I would go old school, use one of the big chainsaw motors with some serious grunt lets see a Homelite super XL around 58cc

I know of a Pioneer 600 I could pick up for $25 that is complete with spark but not running that is 103cc there are plenty of old macks as well & lets not forget the sachs dalmers. the macks go up to 125cc & with racing gocart parts & stroker crank you can get aprox 150cc but you can find inexpensive 80cc saws cheaply

there are plenty of saws with some serious grunt in the 60cc to 80cc class & there are quite a few saws over 100cc

there are guys that race chainsaws & with right fuel turn 25,000 or so RPM but thats in more modern saws. but look at the old saws they turn 6,000 to 8,000 rpm but when you crank them they rumble with power.

by the way I have like 20 chainsaws & for big wood I always pick up one of my old saws. but for medium sized wood or just firewood I will pick a lightweight saw for what seems best for the occasion.

Good discussion.I'll play devils advocate, but I think the chain saw power head idea has merit.Bottom line is that we wont know till someone tries.A few thoughts.The heads were made to move a cutting attachment thru wood.At any given time the cutters were made to have the least amount of friction possible.Reduce friction and you reduce the need for torque.My oldest power head from 1952 weights 27 pounds and looks like a board tracker motor.My newest is 13 pounds and use'es the most friction free cutters of today.Another ration of trade offs.Cut wood or haul bodies,sometimes you do both!!
