....buddy brought it over, says he pulled the spark arrestor and baffling out of the muffler and now it loses power in a cut. He fired it up and was revving it at WOT and it was just screamin. I can tell right away it's running too lean on the high end. I told him to shut 'er down before he fried it. Is that saw supposed to scream away at 15K RPMs? I'm gonna richen it up for him and cut a lil with it, it's pretty scary now but when I am done with it it'll be an absolute weapon. This appears to be an older 200T. Do all of them not have limiter caps on the carb. screws? It seems like there's none on this one, which is a good thing.
