OK, well those rings just can’t be OEM rings, and the big end gaps caused by the flat ends could surely explain the low compression readings… It seems strange that those rust marks did not go away while giving it the 50 cent hone job with the emery cloth, which concerns me.
You have got it back together now, so go ahead and try it, but I think you ought to go ahead and order the proper OEM rings…65PSI is pretty marginal for this engine, especially seeing that it has new rings…
I am very interested in finding out just where you got the flat ended rings, and if they were portrayed as OEM equipment…
If you order the new rings, please do not reassemble until you have checked ring end gaps in the cylinder, along with side clearance on the piston…
