Here is the piston, hopefully its clear enough. The first and second compression ring is basically even with the piston, I am pushing all rings from the backside on this photo and the only one that is coming out at all are the oil rings and the expander. I tried to mess with the two compression rings and I can move them but not very easily.
To clean the carbon deposists, anyone have any recommendations for a good products I can soak this in? Since this is aluminum I am assuming steel wire brushes are a big nono, maybe some copper wool with some good dissolver?
Thanks.
