It could be, if it were not flown very much. It looks like that Enya needs a carb and a muffler. There`s a section here for glow engines along with Enya, SuperTigre, etc. You might be able to get some parts for it. I`ve got a Enya .40 I bought new in 1995 that is still running fine now.
Nice to see that an old model warbird got rescued. Good luck on your project.
