Curt;
I purchased the fractional O-ring cord splicing kit McMaster Carr #  
9694K21 with Buna-N . They also have Viton and silicone options. I plan to  be at 
Portland next week. You are welcome to make a few with the kit. All you  
will need is a fresh tube of super glue. The kit came with a nice selection of  
Buna-N cord that I will never use up.
 
Tom

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.

This link  might help this is from MSC it is for Viton  o rings but they 
offer about 8  different   materials.
