o ring part numbers

[peanut]

can anyone help please with part numbers for O rings for BS38 78-79 carbs.

I need the part numbers (or the sizes), of the needle jet and mixture screw O rings .
I'm suspect that a standard Viton o ring of the correct spec would probably suffice if anyone can suggest substitute parts I'd be grateful thanks.

I have tried searching boats and powersportsplus but given up trying to navigate their websites ...impossible !

thanks GLJ talk about searching for a needle in a haystack !

I think I have a couple of part numbers but the description is poor and the image even poorer so if anyone can give me the info I'd appreciate it
