Crazymanted,

If you you just bought that chainsaw recently it might not have any adjustment screws. A guy in my club who works a lot with lawn tractors and small engines said that the $#@%& EPA is making small engine mfrs. sell them with no adjustment screws, which screws us!! The weedies and chainsaws used to have both adj. screws, then they plugged the idle screw, and now it looks like they're plugging both of them!

Your only solution might be to get an aftermarket carb from Carrprecision or wackerengines.com, or a repair shop. Unfortunately, that will cost you another $40.
