o-ring carbs

[alinus65]

hi,
I am dismantling one by one the carbs of my Z1b.

While reassembling one carb I found one black o-ring which now I don't know where I should fit it.
Apparently the are two of those o-ring out of 4 carbs...(not sure about that).

Here the photo.




help me please.

what are the dimensions of the o ring? the only o rings that i know of in the carb are the ones fitted to the drain screw/ nut on the bottom of the float bowl

it is 10 mm diameter and approx 1.4 mm thickness.
strange thing is that I found only two o-rings out of 4 carburettors I have opened...

I think there are o rings that size under where the choke mechanism screws into the carb body

Some times people fit an o-ring to the joining tee piece to stop leaking, so if it's not from the carb itself it may from there.

Just taken some measurements from a set of VM28s chokes and the O ring is 11.5mm OD x 1.5mm cross section .
