husqvarna chainsaw 3120 xp starts, idles, runs good when cold after running 20-30 minutes it is hard to start.?
Question: so it will not hang after running 20-30 Min. own or place a new cap every day an air filter as pure, this is a carb adjustment or could it be somthing else?
Answer: If you decide to change or clean a boost every day, and it happens when it is hot, but works well when cold, it sounds like an air leak or a plugged choke severely blocked. Perhaps many accumulate in the carburetor, but if it idles cold dry, probably not.
