Technical cackle motor piston rings

what are you guys running for rings on your fuel motor cackle engine please

 

0.17, 1/16 and 3/16's is what it used to be. I don't know that anything other than 1/16, 1/16, 3/16 is necessary because there's no load on it. I haven't been involved in a while, though.

 

my ross are 1/16 1/16 3 /16 so total seal at around $400 or nice set from hot heads for ;ittle over $100.
