Bike was running lumpy after been sat for a while, so i took the carbs off and cleaned out all the jets on one of the crabs i took out the float needle and the brass seat, put the crabs back in the bike run fine until petrol came flooding out from one of the small holes at the base of the of the carbs {see pic} has anyone got any ideas on what might be the course of the fuel leakage?
Thank you in advance

Second picture shows where i think the fuel was coming from
Most likely one or a few of the float valves aren't closing properly so take the bowls off and re seat them and then don't turn the carbs upside down and it should fix the problem. Were they flooding before you took them apart?
no they wasn't flooding before i took them apart to clean them out do you think it would be worth my while getting a carb kit {x4} new o rings and such?

Ok so i have the carbs off again, have taken off the float bowls, taken off the float and needle for the carb that was leaking when i went to take out the brass collar the the needle sets in it came out very easy that's where the problems was, on my visit to a Wicks store on an unrelated issue i came across a packet of O rings mmm i thought to me self i wonder if they would do as a quick fix, so i got some fitted them to the carbs put them all back together and hay-presto job done, don't know how long they will last for as they are O rings for taps and not fuel we shall see!
Forgot to mention some of the O ring will not fit to big or to small the risk is yours i have done this as an alternatively cheep fix and would condone getting the right ones from dealer i just like to try and find an alternative to the problem!
Good call. Obviously not a permanent fix because the petrol will probably eat through them in time. A good temporary fix to get you mobile again whilst awaiting the genuine part. Well done.

Ok i have rebuilt the carbs checked and refitted, still the same problem running unevenly! took the carbs off again striped and rebuilt them adjusted the air intake screws and bench balanced the butterfly's refitted the carbs took the pugs out cleaned them put them back in reconnected everything started her up and still not running right, ok i thought coil pack so i changed it still no difference mmmmm ponder ponder ponder adjusted the TPS that was out started her up still no joy felt the exhausts 4 3 2 are hot as you would expect not so No1 could put my hand on it {not for long though} No1 cylinder is firing {took the plug out and turned her over and am getting a spark} does anyone have any ideas as to what it might be? Also while the carbs were off i turned her over covering the carbs inlets one at a time and got good suction on all inlets.
