Fuel leakage problem.

So, been working on my 1974 evinrude 40 horse. Rebuilt carb and everything was o.k. ran rough, so new plugs, points, condenser, and starter solenoid.. Now when I crank engine gas runs out of the front of the carb. Engine might start or it might not. After I did the points and condensors plugs it would run fine. No problems. Now it's sporadic. Bad carb rebuild? Possible wiring issue causing sporatic power failure to the coils? I did have to bypass the kill switch wire with a new wire, the one on the motor to wire harness plug located inside the motor cooling was bad. I replaced key switch, could this be a problem? Too many variables and no enough common sense on my part. HELP

OEM carb kit? Fuel spilling out is usually a stuck float. Cheap kits are not always good and have mismatched parts. Float level set correctly?

I checked float level per this site, I, unwillingly, am going to pull the carb again and check things out, I did use the original float, but I did a float check by holding the float 7p and tried to blow through the gas inlet tube and it sealed like it was supposed to. But that was a several weeks ago. Cou,d my fuel pump be pumping to strong. I replaced it when I started working on this boat earlier this year.
