Small rubber washers for petrol tap

[ukjules]

Does anyone know where you can get the small
washers for a typical 80's petrol tap ?

Specifically I need the ones on the
prime screw bolt. as per picture.

The larger one I think is a dia 3 ? 1mm.
That's what I have and put in to test.
The lower one must be dia 2 (or less) ? 1.

Reason: I think it is these washers that are causing tap to free flow. It's worth a try to see.

Only ask if someone says ' yep you need these ..... from ...."
otherwise I'll get a pack with some dia 2 ? 1 from ebay and hope that fits the smallest.

Make sure any you buy are VITON/FKM rubber and nothing else.
The Ethanol we now have in our fuel will destroy anything else in no time..
There's a couple of UK sellers on Ebay that i buy Viton 'O ring kits from for the VM carbs and the ones for the mixture screws etc may be the size you need so worth giving them a call.
Here's a link to one of them..

Many thanks. Added to favs.
Shame they don't put the sizes but they look correct. I'll ask.

Update.
asked him and he said he had no idea the diameter of them. I replied does he possess a ruler and have had no response .
UPDATE On UODATE:
EBAY CHAP RESPONDED AND NIW VERY HELPFUL.
MEASUREMENT NOT NEEDED NOW
(((I don't suppose if you find yourself bored, in the garage with a ruler near said washers you could measure ......)))

You will need to measure O rings with a digital vernier gauge, especially with O rings of that size.
Attempting to measure them with a ruler will give you absolutely no accuracy of the ID and width of the O rings.
Same goes with the dimensions of the screw you want the O rings to fit. You cannot possibly measure it accurately enough with a ruler.

the guy I asked. Was gonna say English humour but you are in uk.

Would have measured them for you ( i have a couple of accurate yard sticks in the shed for that sort thing ) but the last set i had is now sitting comfortably in a rebuilt set of carbs which are enjoying life on a running bike.
Looks like Brian has got you sorted now though ?

Well he seems to have 2.5mm OD ? 1.2mm as smallest. This might work for the smallest.
I will consider if I an afford such an expense after the masses of issues I have on all 3 of my working bikes now.
