I don't think mine has a limiter on it, I've seen over 15k while adjusting the carb. I leave this saw rich because I often work it fairly hard noodling.
Looking at your SN, it looks like mine is a little older. In all fairness, I've never really taken mine apart to see what coil/FW is on it. I've never even looked at the carb, but since I'd like to rebuild it I guess that's something I'll be looking into soon.
You probably have the 1201 flywheel with the 1122 400 1300 'dogleg' style coil.
