Briggs med flo jet main jet o ring size

[J beal]

Hey buddys I'm looking to replace the o ring on the lower jet " bottom of carb " looking to see if anyone knows the size of said o ring thanks

a lot of O rings aren't found in a universal assortment...… "just" enough "off" so that you gotta go back to "them"..... and you gotta be careful about material they are made from as the wrong stuff will disintegrate.
