CB500 carb O ring sizes

[Seabeowner]

Anyone know the sizes of the O rings for the float bowl and main jet?
Seen a thread that suggests 68mm x 2mm for the bowl. My measurements came out at slightly less I/D. Buy in quantity and they cost <50p.
Main jet maybe 6mm x 1.5mm, but may be too fat.

I sussed out the float bowl size in Viton and told Trigger ..think he may be able to provide them

Thanks. 
Think the jet is 5 x 1.5 ish not 6. I measure the ring off the float valve holder.

4.2 x 1.1 is what Honda say in a very early parts book that shows all the gaskets and O rings as seperate parts

Thanks Bryan. I've ordered some Viton 4 x 1.5 and will post how I get on.
