i haven't run the dolmar, but you can see from the parts list that it is the same saw as the echo 3400. that's a design that is more than twenty years old and has been rebadged by other companies besides dolmar. i can't find any performance data on the dolmar site but i doubt that it will spin faster than 10k. the reed valve is it's limitation. i've had a few of the 3400's and used them in the tree. they are a reliable saw with a wide power band and inexpensive too. if you live in a wet environment, like norcal, in the winter they have trouble on rainy days. the felt air filter gets glogged.
again, i haven't run this particular saw, so i may be wrong. it would be great if you could make a comparison cutting cookies with the 330 vs the 3410. you can see my comparison with the stihl 020 the link is on page one of this thread. both the 330 and 360 cut faster than the 020t (the model that is the same as the 200t but with a better carb). all three saws were fitted with new chains, off the same roll for the test. as bikemike has said, the echos come from the factory tuned for the epa (and probably sea level.) i live at 6300 ft. so i don't have the luxury of running any saw with factory tuning.
