Title: OS 35 FP RC Needle
Post by: Allen Eshleman on March 29, 2017, 05:48:57 AM

I have an OS 35 FP RC which I bought off the bay.  I think I robbed the needle for another engine.  Where can I find a needle for it?   Or, would be glad to sell it as is for $30.00 plus shipping (Send me a PM).  I have never run it.  Tried to post earlier but hadn't reduced the picture size.  Thanks for any help.

Hopefully this picture is better.

I couldn't find the needle needed on Tower. Maybe it's there.

Also I have a stock 40 FP venturi.  I don't know if it would fit.  I see CL NVA's on tower and on the bay. 

Would the old venturi need a new O Ring?

Does anyone one have a needle laying around who would sell?

Thanks ahead of time.

Needle for 3A carb.

Oring for 3A, you can use it for C/L venturi.

You can use FP40 venturi for 35, too. Both OS stock engines use the same venturi and Oring.
