I was clearly mistaken. I was under the impression that all OS AX series engines had the angled needle valve. Not so with the .46. However, it does have the remote needle valve assembly, so your fingers are safer than they would be with the closer needle valve assembly as with other engines (including OS).

However, I am certain that you will have great performance out of this engine. Also, just be careful with handling of the engine. That needle valve assembly is made of plastic or phenolic or some such material and can.. and will.. break if not handled carefully.

The good news is that the assembly is available as a replacement part.

Tighten the little screws that hold the assembly onto the metal mounting plate, but do so carefully. Don't 'overtighten' it. Make sure it's snug and leave it alone. Perhaps a drop of 5 minute epoxy on the ends.. THE ENDS of the screws may help keep it in place. Rotate it as you need to after you decide where the engine is going to go and where you want the needle valve to point towards, and then secure it in place.

As I said, you will enjoy this engine. It is powerful as well as quiet, start well and easily, and very easy to maintain. Get some after run oil.. marvel mystery oil, or even Mobile 1 synthetic oil, and put 5 or 6 drops in the engine after the days flying, and after you drain the tank and run the engine dry of fuel. This will keep things lubricated and free of moisture.

Let us know how this works out for you.
