Ive finally got my carbs running nicely, trumpets and new super 4 plugs fitted made a massive difference, F16 emulsion tubes should be here tomorrow, now for my little problem, my carbs are fueled from left to right, and after i ran it for a minute or two earlier i found that the carb furthest from the fuel inlet was dripping fuel during and after it was run... the idle is set to about the same as the other three, which is weirding me out a little bit... i think i need to get a regulator and plumb in a return pipe on the fuel circuit, which should hopefully cure it.... any ideas anyone?! cheers folks...

what kind of fuel pump you using?

the standard mechanical pump, did alright on the sport so it'll do for me for a while... a facet pump is still a bit big for my (predicted (optimistically!!)) 105ish bhp...

it looks like its dripping from the screw which holds the tab on, i think it might be the little cover on the bottom of the carb, need to get a little mirror and a torch to see exactly where its coming from...
