2004 z400 problems! Need Help Please!

[quadfreakz400]

Alright here's my problem.... i had to replace a nut on a bolt for the shock mount so i stood the quad up on the grab bar and took out the bolt and headed to true value to get the nut i needed. well true value was closed so i headed back home but forgot i left the quad up on end till the next morning now the quad won't run.... when i looked in the air box it was full of gasoline, the oil is also very low. It has spark, I changed the oil, changed the spark plug, opened up the carb and it looked clean..... still not runnin

Any Suggestions

wont run or wont start?

[quadfreakz400]

both.... it just turns over. a little update of what i've tried... i completely disassembled the carb and cleaned it with carb cleaner... the fuel is getting to the bowl but i guess its not getting fuel to the engine...i just don't know what to do anymore...

ok, i want you to get some thing like maybe a rubber ball ,place it over the intake bell of the carb and then try to start it , be ready to take the ball off if it tries to fire . it may be that the carb needs priming

choke it and it will start the reason is cause the carb is completely filled with gas mine does it all the time or there is a bleeder valve on the bottom of the carb you can loosen that let the gas drain out then try it
