Hello, I just found your site and wondered if someone could offer me some help or advice.
I have this old FUJI 29 engine that has not been used for about 30+years and the last 12 months has been stored in my sisters cellar. (not the ideal place for model engines). Consequently, the engine is seized solid.
I have tried soaking the engine in various fluids but still it won't budge.
I have tried parrafin/ sewing machine oil/cellulose thinners and WD-40 so far.
Any tips or suggestions would be most welcome.
I was thinking of getting an Ultrasonic cleaner anyway, to try and free it up.
If I did this, would the engine need to be dismantled or could it be cleaned whole, as it is?
Thanks for any help.
