Best bet on a 210 is to get good at sharpening chains. You could swap in an 025/023/021 carb that is fully adjustable and open up the muffler some, but it is still 35cc. I'd start saving for a bigger machine, and use the 210 for what it is. With a sharp chain and 14" bar, they are great lightweight limbers. I have used my 023L (about the same power as 210) to cut firewood before, but only in a pinch. I like running saws so taking a little longer did not matter to me.
