Damm didn't make a note of emulsion tubes, its got 145 mains and 55 idle which I think are too big. I've access to a bike carb balancer, can you get away with attaching them to the vacuum advance takes offs? Just though you needed a specific vacuum balance take off point 'higher' up the carb?
Yeah, looks like you've got stock parts in there... Idles might not be too bad... you've got the fine adjustment screw on the base of the carb (one with the spring on it), that allows you to lean off or enrichen either side of the actual jet... You'll have to have a little play and see how you get on!! As for the mains, you'd probably be better with a 130, maybe a 135...
