I don't know jack about servicing watch movements, although it sounds like a hobby that would be hugely rewarding, hugely frustrating, and aggravating to my wife for (n) reasons. All the more motivation to take it up some day....My man!
I finally finished working on this Hampden Model 2 108 D in flag, got the positional adjustment mostly sorted for 4 positions:
Was a real pain because the center wheel (of all things) pivot was broken (yet somehow the hole jewel wasn’t!?!). So I had salvage a center wheel out of a similar Model 2 parts movement, but then do a lot of manual (very careful) re-machining of the pivot due to tolerance differences.
Now I’m trying to salvage this Elgin which someone pumped motor oil into:
The balance hairspring might as well have been dipped in crazy glue. All that stuff that looks like rust is globs of congealed, dried oil. Naphtha didn’t do crap (nor did the cleaner), so I’m probably going to look into my chest of “de-correcting the grain” solvents. Hopefully I don’t have to re-shellac the pallet and impulse jewels.
But anyway, my lawn equipment abuse & repair experience might come in handy for your issue. Consider trying this stuff for your parts. I'd be willing to bet it's safe for your small parts (carbs use brass, steel, and aluminum) and I have found it to be insanely effective at stripping nasties off of carb parts and related paraphernalia.
