I am in need of a needle valve for OPS .61 Red head side exhaust.

Thanks

Chuck

Have you tried Singapore Hobby Supplies? They tend to stock up on OS engines. Drop them a mail.

OPS, not OS.

Thanks for the note.

I'll check my collection.

Chuck,
I do have a OPS RC 60 (Blackhead). Maybe it is the same carburetor and if so, I can do some measurements and make a drawing of the needle if you want. The mounting is like the Supertigre needle.
I did make a picture of the engine.

does it have the slide valve carb or a perry or other type, i may have something that will work, it would help if you posted a pic of the carb and engine

OK, ha, somewhat wrong about the motor.

It is a Rear Exhaust, red head, rear carb and is a .60 not a .61.

BUT.... it does have a carb like the black head pictured about.

I will post pic tomorrow when I can get my adapter.

So Gents,

Chuck has a little problem with trouble shooting. Does not have it all very well organized I think.

While we are all waiting for the moment he does find his adaptor back and after that we all can look for a needle valve it was a good case already do some investigation how big the problem really is.

Do we have to look for a OPS 60 (and of course no 61!!!) Red Head rear exhaust (1) and rear carb needle or needle valve? (Chuck?)
Or can we look for a needle of an OPS RC 10 front carb and side exhaust (2)?

Or

Do we have other possibilities in the future, for example the needle valve of an OPS 40 side exhaust (3)?

The answers is, “Yes, yes, yes!�

If the carb is the same of a (2) engine than also a (3) engine needle probably will fit, see my picture.

So we are all waiting for Chuck, with his OPS powered Mississippi Queen with belt drive!!

His OPS powered Mississippi Queen with belt drive??

Yes because I am also looking for the reason why he did call it a side exhaust engine!
He probably will call a pusher engine a front exhaust.

Chuck, it’s all fun and we are waiting, or do we have to look for an adaptor.

Here it is gents.

Mark, OPS marine engines of the same size can be acquired at auctions for under $100. you might pick up that carb needle you need and even more repair parts. even further, marine versions can be converted to airplane mode with a couple of hours effort.

Chuck,

I did make a picture of the same angle.
There is one more adjustment screw, see the red oval but I think the needles are interchangeable.
When you want a drawing of the needle. let me know and I make one, also with the thread size that is used.

Success Cees

Did you check out the new thread about OPS engine distributed out of Cananda? Pitstop just posted it and says they contacts have been varified.

There is no 2nd screw as in your picture, no open holes.

Thanks all for the help.
