Fuel leak from carb

[Peter Clayton]

Sorry about the delay,thanks for the suggestions,I know the float is ok so I'm going to try the float hieght in the next week or so, (I am away from home at the moment). Hopefully this will sort the problem, if not I will probably look into fitting a S U carb.thanks again and will let you know the outcome.

Not that I needed to rectify the fuel weep on stopping, but I decided that fitting a SU in place of the Zenith would be a positive upgrade. Having an ex Mini carb (1.25) I thought may as well see if it will operate, I've seen reports of others fitting them so gave it a go. I manufacture a manifold adapter to rotate the mounting bolts to suit and increased the manifold inlet diameter to as large as practicable . I checked which needle/spring combination would be best to start with and fitted an"AN" needle with the existing spring. The engine fired up instantly and gives improved torque and acceleration . No idea of fuel consumption but spark plugs would indicate correct mixture.
