Leaking Weber twin choke carb

[OldSkoolRS]

I have a problem with a leak from the petrol line into my carburetor on my 1979 RS2000. I don't know if this pipe can be removed/swapped or whether it is somehow 'pressed' into the carb body, so may not be replaceable?

This picture shows a similar carb to mine and I've marked it with a red arrow to highlight the bit that is leaking on mine.



While I can buy a new replacement, I have a lot of other parts to buy to get this car back on the road, so if I can replace this 'stub' and fix the leak, then I can just use a carb kit and refurbish the carb.

I have previously replaced the pipe and jubilee clip that connects to this 'stub' and it definitely leaks from the body end rather than where the pipe fits around the tip.

Thanks; kind of what I thought regarding the lack of obvious thread. Not sure I'll be able to plug it with something and it's a bit risky if it then starts to leak a little while after, especially if I spend the next 3-4 months getting it back on the road only to set fire to it on the first drive.

Tap that and fit a barbed fitting , that part as been the cause of many a fire as the carb warms up the brass fitting falls out firing fuel all over the dizzy etc you can guess the rest this equates to around 9mm so you should have to open that port out little to tap https://www.ebay.co.uk/itm/232895679481?hash=item3...

That is an excellent suggestion; I have plenty of taps, so just need to order the one from your link. Then I can just buy a carb repair kit so I can strip it and give it a good clean as it's been laid up for 20+ years and I haven't run it for at least 8 years.

Thanks Paintman. I gather the V6 used a similar carb; 38DGAS (or something like) and some RS2000 owners fitted them as an upgrade to the 28/36 (at least I think that's what mine has).

I'm going to take the plugs out and see if I can turn the engine over by hand, if so I might try one of the ideas above to fix the leak and see if I can get it running again. I'm going to partly strip the engine down anyway, if only to clean and paint the 'bay and the engine itself up a bit, but would be good to hear it run again.

Good enough an excuse to fit twin 45s.

True, though that'll only set the anoraks off more when I do advertise it. Plus it'll lead to other upgrades and then it'll never get back on the road this autumn.
