Some of you might remember last time I used my MS461 the idle started running the chain pretty fast. Well I just got to looking at it. I don’t know what the L screw was set at because I was turning it by the time I realized I engaged it. The H screw was close to where it was supposed to be, all the way out. I reset the L screw as per the Stihl manual I found online (All the way in, & back out a 1/4 turn). I also put on a new Stihl air filter. I had an aftermarket filter that was too fat to fit all the way in, and wasn’t sealing. I cleaned it with carburetor cleaner, with the saw bar pointed up, so everything would run back out. Then I let it air dry a while, before putting it back together. The spark plug didn’t look perfect, but still some life left in it. I ordered two new ones. It started up easy, and the chain was barely inching forward. I couldn’t set it per the manual. It says turn clockwise until the chain starts to run, then back off 1-1/2 turns. It died before I got to 1-1/2 turns, maybe a little past one turn. So I just went back to where it started running the chain, and backed off just enough to stop the chain.
