Hey you guys
I'm after some help with the pilot screws on an nc30 carbs

behinde the screw you have a spring, a washer and a o ring (seal). Is it possible to purchase just the o ring on it's own, if so does anyone know where from or got a part number

cheers phil

I believe they're part of the honda float bowl gasket kit (pricey!), you can't buy them separately.

Any suitable sized viton (fuel resistant!) o-rings will be fine to use.

I got some from a massive pack of various sized orings in halfords. They fit a treat on my triarm. The whole pack is expensive, so I found an open pack . If they have them there though you will get them in any decent motor factor
