Oil coming out of chainsaw muffler
I have an old McCullough Eager Beaver 2.0 chainsaw. After I start it, it runs rough for a few minutes and then dies. Oil is coming out of the muffler. I have replaced the air filter and also installed a new sprocket drum. Any help you can give me to get this saw running is appreciated. Still trying to recover from 2 hurricanes.

Could simply be that there is too much oil in the fuel mixture? Also, if the carb is in need of repair or the choke is not opening all the way, it could do this.
