Gas keeps pouring out of the front vent tube at the choke air horn.I pulled the needle and seat assembly out thinking that maybe it was sticking. I cleaned it good and screwed it down to the same location it was in. I went to start the car to make the final float adjustment and the same thing happended. Any suggestions. Thank's Russ. By the way the carb is a holley 770 street avenger with vacuum secondaries,with only 200 miles on it.

Usually the problem is floats too high, dirty or worn out needle and seat, too much fuel pressure(5 to 7 psi is good). I had a bad metering plate gasket cause problems before also.

What fuel pump are you running?

Reset float level...should be done Any time u pull the needle out.

What fuel pump are you running?

The fuel pump is a holley 80 gph mechanical.

Problem solved guy's,the float level was too high. Thank's for the help:waving:
