Fuel leak from carb

[Colin Wilks]

If the float is too high surely you would expect over rich running from the off due to flooding, not just a drip when stopped? I am new to sevens but had this rich running problem on my land rover's Zenith 36IV - after rebuild the float turned out to be 1.5 mm high (4.5% out). Here I would be thinking about more oomph from the newly rebuilt pump and a sticky or worn needle valve.
