    Have no idea what quality is being sent out now?
    After getting a poor quality Avenger carb, I just disassemble them, and make sure everything is cleaned out, and put them back together.
    The issue with the carb mentioned was brass debris in the jet channel of the metering plate.

    So, getting back to the OP's post #28 it appears that somebody replaced a factory screw with a much longer screw that prevented the float from rising high enough to shut off the fuel flow when the float was adjusted correctly. The only way I can see the car running good with that scenario is if the float level was set so low that the needle shut off before the float hit that screw. Maybe some debris got into the needle/seat and that started the problem with fuel running out of the vent. When the OP changed the needle assembly, unless the float was reset at a very low level, it would continue to vent fuel because of the too long/incorrect screw interfering with the float. Kudos to the OP for spotting that interference problem and solving it 'hot rod' style...Good on you!
    Might look into a fuel filter that traps smaller particles to ward off a repeat performance.

    I’m not sure why it would be happening suddenly after I had run well for a period of time. Trash in needle/seat? Start with basics first .
