Thanks - that's a lot of weight if it is just the motor head ... .
As for the power figures, I have seen those seriously critizied
somewhere and have also written about it at another forum
- but I have forgot the details - 13hp is about 50% more hp/
displacement unit than modern saws, after all ... . Clearly,
there are some old big two-cylinder two-man saws with 3/4
pitch chain etc with more power than is considered healthy
nowadays, but I do a little distrust Stihl 090 should be one
of those just from what I sort of found by "looking around"
a couple of years ago - not that I have never seen one, held
one or even less owned one
... .
I mean if your take your Kawa 750 cc 1970-ies two-stroke
70-75 hp (which is again most likely an exagreagated pap-
er figure) or so motorcycle to a modern engine tuner/build-
er he/she gives you like 125 hp with lowered emissions and
fuel consumptions as well as bettered driveability properties
together with a back-wheel test protocol to certify what you
have
