Something like Marvel will help loosen up the dried oil. I have some Macs sitting for 40 years and not any problem with loosening them up. Mac chainsaws sitting for 60 years rarely have failure on those bearings. Hopefully castor was not used for the oil mix. It tends to gum up and dry out bad. Sometimes even rust.
You can also remove stuffer and pour in gas marvel mix then let sit for a while. Shake up and rotate engine over. Doesnt need much to coat everything.
Thanks for the suggestions. I will try them.
