The 334XPT, supposedly down on power over the grunty-as 335 and 338, pro-saw performance tuned down for backyard Bill, don't know how, possibly narrower ports or something but open the muffler, triple the size of the exhaust outlet and you'd get 1.5kw easy enough. The husky engine decades old and the echos latest and greatest effort, the 355, from strip-down pics on this site from the modder crowd, looks similar except the husky engine looks classier with better components. Not bad echo, getting close now, just catching up to huskys ten year old design... hohoho. As for the ridiculous "crank stuffer" B.S. what absolute nonsense, gimme one of those 355 echos as a bush saw, I'd send those crank stuffers flying out the exhaust. Along with a bit of shrapnel hopefully.. hohoho
