Default O.S. 2B carb

I have a couple of 25 FSR engines that both have the 2B carb. I am missing the small spring/clip that goes on the low speed needle valve (throttle arm side) that keeps the adjust needle from moving. Any idea where I can get a couple?

That part has been long discontinued. We'd not know where you might be able to locate the ratchet spring for that carb's idle needle. You'll likely need to find a "parts" engine or a carb from an auction site or a classified ad in a model magazine. Maybe one of the selling sections of the RC forums, such as the RCU Marketplace, will help you.
