I have a OS61RF Hanno Spec in an LA1 that I have been flying since '92. I started having problems with the engine and sent it in to Hobby services to have it checked out. They replied by saying that it seemed like a pump problem but since parts were not available they could not work on it.

I'm thinking that maybe i should just go ahead and get a new engine.

Question: Should I just go ahead and replace this 20 year old engine, with what, or should i try to get it worked on somewhere.

Thanks!
