Overfloating carb and smoke from intake manifold

[IceFJ]

I hope that you are not doing the same beginners mistake as I did when I first started to play With the carbs, that is adjusting the air/fuel mix screws in an attempt to sync the carbs and overseeing the actual sync screws that are sitting lower on the carb.
At the time I did somehow manage to get the engine to run nicely but today I see how out of adjustment everything was.

Also, without Reading through the entire post again, has anyone thought of the possibility that the carbs might be set up for gravity feed but are actually run With fuel pump causing the initial problem of overfloating and the issues that come With it...

Just my thoughts in this....
