Hey Otto, where ya been man? Good to see you back! I`ve got the 353 and haven`t even used it, want it to be clean when Dennis goes inside. I like my 346 alot, I think it makes a great firewood saw if you are mostly doing tops or stuff smaller than about 14", same ballpark as an MS260 would be in for the most part. The 353 should have more grunt with the extra 5ccs of displacement, and guys who have run the 351(which includes myself) can attest to the fact that the increased displacement does indeed seem to give it a little more stump power for longer cuts in bigger material. In smaller stuff however it`s no contest, the 346 is significantly faster. Peak power at 700 rpm above what the 351 and 353 offer is huge when the wood isn`t large enough to suck the saw down out of it`s powerband. Russ
