M750 carb problems

Evening all, looking to see if anyone can help with my carb issues here. Had the carbs off and cleaned out on the 750 - off the road 10 years I think - actual lumps of gunge and rust in the float bowls. Got everything cleaned up and new o rings etc all fitted but cannot get the bugger to run properly. Running mega rich and fuel everywhere, I'm pretty sure I can see wear on the needles and there is a ton of fuel coming out the tube so I'm thinking that's had it as well. Does anywhere know where I can buy these bits? I can only seem to find a total overhaul kit on nrp carbs for £50 per carb. Wondering if I'm missing something or if I have to bite the bullet here and buy the overhaul kits.



Cheers for any advice

I have just re commissioned an M750 that had been idle since 2005 and my major carb problem was the fuel pipes looked ok but once pressure was put on via the pump they leaked owing to the fact they had sort of dissolved on the inside. All available from Stein Dinse ...at a price!

I got some repair kits off eBay and they worked fine. Much cheaper.

Yeah I've done the float bowl rebuild but the problem now is the needles and tubes are worn allowing too much fuel through, idles all over the place and its running - when its running sorry - its running really bad as its far too rich.
