The petcock is the on/off/reserve valve.

 

yes the petcock is tured on

 

It can be turned on and still be blocked by junk in the gas tank. Turn the valve off, pull the fuel line off the valve, and slowly turn the valve open to see if anything comes out. If something comes out, then most likely it's time to take apart your carb and clean it out, or take it to a shop if you're not confident in taking it apart yourself.

 

Ohh and also check your gas cap vent hose make sure not kinked..

 

i cook my Atv to the shop and it is now working

 

just an idea,I buy a new fuel petcock every year or so..the part is only a few dollars and has some very imprtant filters on it..

 

What was wrong with it?
