I have my brother in laws Poulan 34c 16" chainsaw. I borrowed, broke it (the pulling sproket) bought a brand new Husquavarna to finish cutting down my tree. I waited 7 weeks for this sproket to come in. Anyway got the Poulan working but it cuts out and dies, I have to keep gunning it. I may have adjusted the idle by accident when taking it apart So I read up on low and high idle but I don't think.. in fact I couldn't have touched those adjustments, they are very deep. But the over all idle or what ever it is, just above the primer looks just like a normal screw with a spring on it. So I started the chain saw again and it was running fast on its own. It wouldn't slow down, the chain was constantly moving. So while it was running I was trying to set the idle lower but I couldn't feel the screw and ended up unscrewing it completely. It fell inside the machine and the machine died right at that moment. Took it apart again, I got that Idle screw with the spring on it's first threads. I would like to know how far I should screw it in to be fairly workable. I can't adjust it while the chain saw is running.
