Unhappy carb problem

just rebuilt my 12a port and polished it got it all together and my carb is screwing up when I turn the engine over it starts pouring fuel down in my engine both in the primaries and secondaries even though my sec are not open and the fuel is disconnected and when the line is connected and I just turn on the fuel pump it pours it down the engine?????? what could be the problem its not the floats I bent them where it only opens to fuel pressure its like its pushing air into the bowl to make it come out the venturies?????? anything can help

Was the carb rebuilt? Sometimes the needle valves will stick on a fresh rebuild, which can be remedied sometimes by lightly tapping the top of the carb with the plastic handle of a screwdriver or somethin similar.

Someone please correct me if I'm wrong about this, but I believe I read this here somewhere. Good luck!

You might wanna take the top off the carb and move/exercise the floats/needles. They dont like sitting for long periods. I have that problem on the racecar if I dont go out and start it once a month. Very common problem. You can check the vent solenoid easy. Turn the key on and disconnect-connect the plug, youll hear it clicking if its working.
