KR> Posa carburetor leak

[cruzj12 at frontiernet.net]

My VW runs good but I have?a gas leak dripping?when I open the fuel valve.So I 
shut it off after a few seconds to start it then back on after she fires up.?Is 
there an bad "O" ring I missed or just another process?of adustment on the 
needle?to stop the leak?
