I agree cutting eucalyptus a differnt ball game had a 391 and had to get rid off it the 066 big bore and ported with 25 inch bar will lug it the 391 had no chance of lastingHe'd by running a 16" bar on a 66 with a 8 pin sprocket please explain how that will burn the saw up???
You can't judge a persons decision without know the circumstances.
My 66 has bars ranging from 16"-42" then my 88 has bars from 42"-84".
Yes I do have smaller saws an old 036 201tcm ms170. But for cutting dead dry Aussie hardwoods these saws don't cut it and it will kill them.
These best firewood saw is the best saw setup that can justify the dollars for at that given time.
