fuel filter plugged up? Gas tank not venting? Fuel line clogged?

You have cleaned carbs?

 

[sevenhillsbilly]

i cleaned them when i replaced the fuel T inbetween the carbs i was thinking that even if 3 of the 4 carbs work working it will still kinda start but it wont even do that

dumb question, but is your choke cable busted? My bike would probably start cold on ether with no choke.
