Several years ago I installed o rings in the lower two grooves on  my Geo. 
Miller engine. I tried several sizes from a Chinese assortment that I  have 
and found that they were too tight or loose causing difficulty replacing  
the piston or excessive blowby. I finely purchased a "do it yourself" o  ring 
kit  from McMaster Carr .  They supply bulk o ring  material of several OD's 
and all you need to do is cut the correct length  and stick  the ends 
together with super glue using a jig that  is part of the kit. After a lot of 
trial and error I found that  by making the ring slightly undersized I could 
get the ring to  fit, fill, the piston groove and extend up just enough to get 
a good seal  in my oval badly pitted cylinder. I operated the engine for 
several years  on the same o rings then had the engine sleeved.
