They all need tuning to get them to idle correctly.
They all seem slow and underpowered until they are broken in (about 200 miles).
Carb overflowing can be caused by numerous problems.
The 3 most common:
Not using an in line fuel filter will allow junk to get stuck inside the float needle valve and prevent it from sealing when the float bowl is full.
Float setting needs to be adjusted because it is too high, allowing the float bowl to overfill.
Float has a pinhole and is filling up with fuel turning it into a don't float.
