O.K. I have been out of the RC airplane for about five years and now getting back into it. I have a OS46 LA that only has six tanks of fuel through it and that last flight was five years ago. I did put after run oil in it at the time, but it has set ever since. Now that I look at it I have found it has locked up pretty tight, very hard to turn by hand. If I tear it down and clean it up good any chance of it being able to be used again or should I just make a good paper weight out of it.

When I did fly it I always had it running very rich, but just not sure it worth buying all new gaskets and trying to play with it.
