If they are thin wavy things about the same diameter as the rings themselves then they go in the grooves under the rings

Can I ask a quick favor, would you measure the spigot diameters on both ends of the carb.  Just purchased an aftermarket carb for my SY250R and currently too lazy to remove the original carb.

Its a ring expander, common enough to 2 stroke piston rings. You can run with or without, up to you
