Hi all. Rookie carb re-builder here. I rebuilt the carb on my 40 today and i think i did something wrong. Gas is shooting out of the air vent screw on top of the fuel bowl. I'm assuming the needle valve is not closing all the way when needed. I can't find my book and was wondering if anyone has a diagram of how the fuel bowl and components go together. I think i put the 2 pieces that shut the needle valve (when tha float is up) in backwards. Any takers???
Thanks in advance...
Tim B.
