I'm not sure if this is the appropriate place to post this, if not, I apologize., But I am running a chainsaw this year for the second year in a row and have already went through one crappy homelite one that I got for free, I just picked up a Poulan saw today in much better condition. In this thread someone talked about how revving it too high may blow the engine, they said something about a set screw to limit how high it revs.

Anyone know how this is done or have any tips? Thanks. Also, any tips on chainsaws in general?
