Once again about the infamous carb O-rings. I have measured these sizes (ID x thickness in mm):

Needle jet (emulsion tube): 10 x 1
Pilot air screw: 3 x 1
Float: 5.5 x 1.5 and 7.5 x 1.5
Membrane cover: 4 x 1

Is this correct?

Emulsion tube: 10mm X 1.5mm
Pilot air screw: didn't know there was an O-ring!
Float: 5mm X 1.5mm & 7mm X 1.5mm
Membrane cover: 3mm X 1.5mm

I hope this helps.

Thanks! There is an o-ring for the pilot air screw in some 33 mm carbs.

Just measured again, including the original new rings from Suzuki, and these are my definitive sizes for the 33 mm carbs:

Needle jet (emulsion tube): 10 x 1.5
Pilot air screw: 3 x 1
Float: 5.5 x 1.5 and 7.5 x 1.5
Membrane cover: 4 x 1
