carb problems?

[bludclot]

carbs have stated to leak fuel down into the recess below and yesterday the bike back fired when trying to start and sent out a small cloud of smoke from under the carbs on the right hand side. it feels to be running a little rougher than before and a bit down on power too. any ideas as to what this could be?
i hate to say it but all was fine before ivanising, then the fuel leak started as just very slightly noticeable but has grown steadily more pronounced. just coincidence i am sure. i think it's a carbs on the bench job to remedy myself...

Float valve stuck?

[Falcon 269]

I'm away touring Europe at the moment so not often online.  Just seen this today.  First, identify where the leak is coming from ... is it float bowl gasket area or elsewhere?

Stuck float would manifest - usually - as a leak from one of the overflow pipes.  The rough running suggests possible rich misfire and on older Fazers the culprit is often float needle seat O-rings.  A search here and on FZ1OA site will throw up lots of info on this issue.
