arse - so what do I do now? (drippy carb)

My order of 2 carb rebuild kits from Z1 enterprises arrived to day - damn quick!! - so I fitted the needle valve.

first question - the one supplied is 2.0 but ones fitted are 2.3 - will that make a difference? (pretty sure that is the diameter of the hole)

And if that worries me, and it does a bit, would be ok if I drill it out to 2.3 mm?

And still a slow drip. ARSE!! :twisted:

So that ruled out the needle vavle - in fact I had cleaned up the old one but wasn't sure that did the trick.

So I take off the float bowl, fill it with petrol, put finger over the end of the long thin brass tube and blow into the hose. And guess what??? sodding bubbles!!!! :x :?? :(

Basically there is a tiny pin hole - I cannot see it with my eyes :shock: - in the side but it is there.

So WTF do I do? :(

Solder? Heatshrink? I guess this part is not replaceable so would I be looking for a replpacement float bowl if I do not want to fix by any of the above methods?

Realy want to kick myself in the bollocks as it would have saved a few quid on 2 unnecessary kits, ebay them?

Anyways good news, for it is worth, at least the fault has been found.


Long shot but don't suppose anyone has or know where I can get one float chamber cylinder no.4 - the one next to your right leg - Z1000 A1 VM 26 carbs?

just cleaned the tube with some wet'n'dry - and there is a split down it. :(

a bit of chalk to highlight the split - see the white line along the left edge of the tube in this photo?

A bit of silver solder - and a steady hand.... :??

Or you could find some tight fitting sleeve to fit over it :?:

You're right with plumbers solder / electrical solder. Getting it hot enough to silver solder will probably melt the brass.
