Stihl 017 Starting Problem

[dennis]

I have a Stihl 017 chainsaw that runs great, but starts very hard, if at all, when cold. If I pour a little gas into the carb via the air filter, I can start it. From then on , it will start, idle, and run perfectly for the rest of the day. Let it set a couple of days, and I have to prime the carb. Does this sound like a carb problem, or could it be something else?
