The vent is the 3/16 tube sticking out the top with an angle cut on it.
Could it be your float sunk? Maybe replace that too. Also guessing you set the float level correctly.

ok here is what i did i semi took it apart while on the motor...i disconnected the coil so i could turn over the motor without spark. The float seems to work ok...how to i adjust it to close the needle a little tighter becuase here is what its doing.
If i crank the motor over it seems to hold back the fuel when the bowl is full but than if i wait about 30 seconds it seems to have built up pressure in the line. it slowly starts to fill up the bowl and than overflow it. any tips on how to fix this?

Do you have hard fuel line between the pump and the carb?
The float is set so that the fuel is at a certain level in the carb for correct metering. You set it as by bending the arm metal connected. Do not bend it to close the neddle/seat tighter.

New Issues
ok i seem to have the leaking issue resolved. It did turn out to be the seat and needle at the float.
New Issue: The motor will not rev above 4000rpms It doesn't pop or hesitates just bogs its weird it bogs down above 4000 and runs great up to that point. It also seems to heat up a bit once im there to about 185 motor normally runs at 160 something is going on.
any ideas? Im so fed up with these carb issues I want a new one!
