Maybe a new needle and seat first and then revaluate the problem. any ideas?

If the needle and seat was the problem you won't be able to set the fuel level. With the engine idling, remove the plug on the right side of the fuel bowl. The fuel level should be at the bottom of the hole.
Another easy thing you could do, you can look down the carburetor (while the engine is at idle) to see if fuel is dripping out of the booster nozzles, if it is the fuel level is too high. This will make idle very hard to set (too rich all the time).
If you can't adjust the fuel level either the fuel pressure too high or the needle and seat is bad.
Also I wouldn't relies on the fuel gauge, not accurate. Topped up the tank and do the math. This is the only way to now for sure.
On a side note: you could add an O2 sensor and indicator to the exhaust pipe to measure your mixture. This will tell you if it is really rich or lean.
