Piston Ring Sticking

Hey everybody, so I tested the compression on my FA50 after it was having some issues and found that it was pretty low. I took the head off and the cylinder and found the piston rings were stuck in the grooves. I took them out, and for good measure just ordered new rings and gaskets and such. It seems that no matter how much I clean the grooves even the new rings stick. Any methods for getting grime out? It seems as though the grooves are not clogged and I've gone through it plenty of times. Could it be the metal on the piston itself warped causing tightness? Also is it necessary to hone the cylinder with these new rings? I do not have a hone but if it is worth it then perhaps I will get everything for one. Thank you.
