Thanks again.

The float is OK, though they say you should heat it and put it in water to test properly, no sign of liquid inside and it functions OK when the carb is open and on the car and starter is turning etc. I will contact the carburetor shop today see what they say. I have a Viton tipped needle in my 120 and that sometimes floods as well!
I will also check the bowl vent to see that it was not blocked.
Interestingly the one of the accelerator jets was blocked at the tip where the pipe feeds through a hole in the main discharge tube, very difficult to unblock as the tube is soldered into the body and had to be bent to get it out of the hole. Previous owner had reported poor acceleration and this may be the reason, car was proffesionally restored so it shows these things can get missed.
I have not checked the pressure and am unsure of the best way to do this I hear that some mech pumps do give too much, and regulators can be fitted, with the bowl exposed it gives surges of fuel which splash out!
