carburetor help wantedhi guys, i am just rebuilding my kh250, i had the frame painted and have now put all the wiring back on, (the right way i think) i have mounted the engine and attached the carbs, i just wanted to see what the engine sounded like before i completely rebuilt it all.when i turn on the petrol it pours outta the breather pipes, what have i done wrong..??. .this is basically a learning game for me as i know very little about engines..
thanks in advance to you all

Cosh the carbs with a spanner, the valves might simply be stuck open or have some dirt lodged in them.
Otherwise you might have set the float level too high and the valves are unable to close before the float touches the top of the chamber.
Another possibility (given my experience today) is that you have a sink instead of a float, while you have them in your hand give 'em a shake in case they are full of fuel.. or they might be badly dented which affects the float level.

the bike has been stood ten years, i took them off and cleaned out the carbs and jets, i did not set any float level, i guessed i would have a look at the problem if i got one, all the three carbs are flooding, so then i think all the float levels must be wrong then

which reminds me of the old joke about the mechanic and the customer.Customer asks "what was the problem?". mechanic replies "just shit in your float chamber".Customer replies "how often do i need to do this".

Cosh first, worry later.

thanks wolfman, i coshed the carbs and two of them stopped leaking straight away, but the third one did not, when i took it off i realised i did not put a gasket in the joint  i told you i was learning 
so now i got three carbs that seem to be working, i got a spark at the plugs, why will it not fire up? where shall i start looking? any ideas?
Thanks all...
