Fuel leak at carb; what seal do I need

Recommended Posts

Pulled up after a drive in the warmth today and could smell a little petrol I thought. Opened the bonnet and surely enough the back of the rear Dellorto carb was leaking and making things rather wet. Not good on a hot day! Fortunately there were no Towering Inferno-type scenarios, but I want to get i sorted before I'm out in it again for obvious reasons. I've circled the seal which seemed to be the culprit, but what is that called in parts manuals? I've looked on Rdent and SJS but can't ID it and am not sure the correct name for it. I could possibly unscrew the seal, re-tighten and it be OK for a while but I'd rather sort it with a new seal.

Many thanks in advance for any guidance as to what this seal is called so I can get a replacement ordered.

I did. I found these two, but wasn't sure it was these fibre washers. Looks like I'm wrong though!

I think one of each of these and a new filter may help :)

Hi Dave,

They are the ones.  Follow this link

and scroll down a little to where it says "click here" and it takes you to the clickable patrs diagram where you can see them in context Nos 42 and 46 and filter no 45.
