1957 stock Holley carb leaking fuel bad from primary fuel bowl vent. A TON of people said check float and needle/seat assembly. I did and everything checked out. Well, after 2-3 weeks of trying different parts, turned out to be the small O ring on the needle.seat assembly itself.... Crazy! Small part can cause such a major issue.
