Seals and or rings would not make the saw rev high. More likely the throttle is sticking open after it gets hot. Check throttle position and clean. Get a can of spray carb cleaner from auto parts or the marine store. Spray away till it's clean and check the throttle position again. RPM's only go up for two reasons, and they are both fuel air ratio. One is the throttle is open the other is momentary rev when the fuel supply is cut off.
You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?
Hi, you may try draining the fuel from the float bowl through the screw at the bottom of the carb as it may have become contaminated, try leaving the choke on a while longer, if it still stalls then I would remove the carb and clean the jets and check the fuel flow, checking the float valve action before reassembling
