Hello Randy:
The rings are the standard style rings that were made by McCoy circa 1948. There are two rings on the piston.
Have a great Holiday,

Hi Frank
The 2 main problems I see with these are ( there are more problems but these are the main ones) , sleeve not round or in good shape, many times the sleeve is "mushroomed" and the gap actually opens more at the top, sleeve is grooved or scored, or polished shiny and will not seat a new ring.
The other is the rings themselves are not very tight, and many times are not round, You want the tightest gapped ring at the top groove and the bottom ring a little more open.
When checking the ring groove, clean everything well, use the piston as a blocking/squaring push tool to set it square in the sleeve, check the gap midway up and about 7/8 of the way up the sleeve. It should be the same on that engine, if more open at the top, you have a problem sleeve
