When I do this for customers I'll do a solvent soak and air blow out and work the stuck pawls to both free them up and hopefully dissolve out some of the old now gummy lube. I'll spray apply TriFlow and work that in with motion and air blow out. Then a serious dripping of medium oil (FL Wet is our bench oil) with another round of motion and blow out. Depending on how much oil has remained I might add a few specific drips and end up with a light grease brush dabbed on. Very early on I had a couple of returns because our flush and spray lube while still on the bike all hooked up method wasn't enough to really help the pawl pivots. BTW one can not just work the pawl by rotating it on the pivot shaft but often there's some end play that the pawl can be pushed "sideways" along the pivot shaft. I use a sharpened spoke as my pick/tool. Just be careful if you go deeper and remove the pivot's tiny E clip to not loose it... Andy
