Problem starting Stihl 032AV chainsaw
I'm trying to get a hand-me-down Stihl 032AV cleaned up and running, and have run into a bit of a problem. If I pull on the starter cord without the spark plug in place, it will turn over with a nice, smooth motion. If I put the spark plug in, even just barely hand-tight, and yank on the starter cord, it binds up within the first half-to-3/4 pull. After that the cord will not move unless I remove the spark plug again. The saw was running just yesterday. It has a fresh oil/gas mix. Any ideas as to what may be causing this to bind up? I'm at a loss when it comes to this type of stuff :-)
Thanks in advance!
