Unknown needle valve assembly

[Ara Dedekian]

            Anyone know who makes (made) the needle valve assembly pictured below? I found it on a Fox 35 and it works quite well. The fuel nipple screws onto the spray bar.

My OS Max I .35 has a NVA similar to that one.

I hope the nipple points the right way when the fuel hole is down.

       It will, with just the right thickness washers on both sides of the case.

Definitely from an OS Max 1 29 or 35

        Thanks for the replies.

        I dug into the stash of engines that the needle valve came from and found the twin stack .29, most likely the engine it was originally on.

        I'd clean it up to at least see it run on the test stand except for picture #2.

Ara,

Is the hole in the backplate the only thing visibly wrong with it?

If the hole in the backplate is the only damage, that'd be an easy fix with a bit of sheet aluminum cut to fit the inside of the recess and some JB Weld. But I suspect there might be something else amiss inside!  Steve

          I went ahead and tore it down and found the only usable parts were the crankshaft and con rod. Everything else on the engine was bunged up. Even the threaded bosses on the case holding the cylinder through bolts were stripped.

So, it's a toss up between whether it's quicker to fix what's there or start with a big hunk of aluminum?

Ara,

Sometimes it turns out that way. I was thinking along the same lines as Steve, which was why I asked the question. If the engine had sentimental value, and if I had it all apart, I'd make up a nice wood plaque and arrange the parts on it in an exploded view. Maybe get a brass label that said "My First Big Engine" or somesuch. But then again, I'm not an (intentional) engine collector....

Happy Apollo week,

I have one like that.  But the label needs to say "shoulda used more castor!".

Timmer,

Yeah, I hear you. I'm trying to get the nerve up to look at the Evo 60 in my T-Rex. I flew it at our club picnic on Sunday. Almost, but not quite stupid hot out. First run was near perfect for the calm conditions. Just a tad too slow for line tension in corners. But that big P-47 invasion stripe job looked really cool from the middle of the circle. On the second run the wind had come up so I turned in the needle a bit. About halfway thru, it started to rattle and was not happy. Hope that one doesn't end up on a plaque. It has always had an amazingly good run....

If I have to make up a plaque for the Evo, I'll try to remember to cut one for Ara, too.

Regardless, it might be appreciated (by someone) if you save the good parts and list them on the Classifieds "Free For Postage". I had an early Veco 29 that broke the inevitably breakable conrod. I was 16 or so and only knew that Veco wouldn't have parts for it. Didn't know that a K&B .29 rod (steel) of the same vintage would fit and never break.  Steve
