After finding out that my old Chinese trainer engine had more differing parts than a scrap yard and the needle valve really doesn't make a difference I'm looking out for a new reliable engine for my Cessna 62.
I have an OS 40 or 46 LA ( not sure what it is) used a while ago, in the garage if you are interested.
Bought new used for a few months, then I sold the plane.
Sure we can come to an arrangement.
