I was given a cox thimble drome engine by my band teacher and I know nothing about rc glow engine. I would like to run it but it is 30 years old and hasn't been run for a long time. Can anyone give me some things to do in order to protect the engine after 20 years of not running? I have taken the entire thing part and cleaned the general gunk off of it and added some oil but I don't know what to do next. I found online that 20% nitro soul be good but I don't know if thanks accurate.
You will most likely need to replace the bearings. Use a bearing puller if you have one. Sealed bearings tend to be the best in this day and age.
