i'm fairly new 2 chainsaws but i want 2 fix a chainsaw that i picked up dead from a buddy, it is a stihl 017, it had a bad carberator so i replaced it w/ the carb off of a stihl 021, which has the hi /lo adjustment screws as well as the idle adjust. it fires right up w/ the choke in full open position but when i switch to half choke or gun the throttle, it dies. when it fires up on full choke, if i feather the switch towards half choke i can get the saw 2 reach full throttle but once i let the switch engage in the run position it dies out.......i've removed, inspected and reinstalled the fuel pickup line and it looked fine. i've set the hi n' lo screws to the recommended default positions ( 1 full turn counterclockwise from seated) and the idle adjust is set about 2 full turns counterclockwise from seated...i'm using freshly mixed 92 octane fuel w/ stihl mix. the little rubber cork/valve thing in the top of the gas tank seems to be as it should.....do i need 2 set the hi n' lo /idle adjustments differently or......??? any help/insight would be VERY MUCH appreciated. thnx =]
