Xbr carb o ring question

[hyperbimduke]

Hi all.
Bought a refurb kit and there are 2 o rings, one small for slow running mixture screw but where does larger 7mm one go?

Try it on the drain plug 👍

Thanks for that, took out drain plug couldnt fid where an o ring would go, do you know if later XBR's do have an o ring on drain plug?

Sorry, my XBR doesn't have the original carb. I had a look in the service manual and on cmsnl, but there doesn't appear to be any clear indication on the diagrams. Hopefully, someone will know, instead of guessing 👍

Or, Dave Silver do a refurb kit, so a phonecall to them might get you the result.

Hey, had a closer look at the drain screw and there is an o ring groove and it fits. Thank you, mine didn't have one on but didn't leak either, happy now as nothing worse than having bits left over...
