O-ring size

[P09luis]

Does anyone know the size of the float valve seat o-ring from a 82 gs1100 carburetor. I got a metric kit of Viton/FKM o-rings but some fit too loose or too tight. Thank you

-010 (Dash 10) in AS568, Buna only. Should be readily available.

So I got this orings we use this kind on machines in the oil fields. So far looks good, I even tested by running fuel on the carbas to see if it leaks.

That's a good thing, because I gave you the wrong AS568 number! The -010 is the correct size for the fuel tubes, not the inlet seat. For that, a -903 fits perfectly. This size equates to 7.65mm ID x 1.63mm cross section, which is extremely close to what you have.

Well I order a few of the size you mentioned before to have in hand, I like to have this type of stuff on hand. Thank you
