*1EA OEM EMULSION TUBE O-RING (NOT IN ALL CARB KITS) CT90 ATC90 (84L)
EMULSION TUBE O-RING (NOT IN some CARB KITS)
WORKS IN STOCK CARBURATORS FROM--CT90'S K2 TO 1977 ALL ATC90'S 
(NOT INCLUDED) BUT, WE GET THESE FROM AN OEM CARB PACKING KIT HONDA # 16010-102-305 THAT WE HAVE PIECED OUT OVER THE YEARS
 
ALSO IN THIS ORING KIT IS THIS SMALL ORING THAT TOO MANY PEOPLE, WHEN CLEANING A CARB OVER LOOK! TOO MANY TIMES PEOPLE DON'T KNOW THAT THE EMULSION TUBE WILL COME OUT OF THE CARB BODY.
THIS O-RING GOES IN THE TINY GROOVE AT THE TOP OF THIS TUBE. MOST CARB KITS FOR SOME REASON DON'T INCLUDE THIS SMALL ORING.
