Carb rebuild

Pulled the twin Dellortos off the car this evening. As the car hasn't really been run for 16/17 years I thought they might be a little worse for wear.
In the end they weren't that bad, just some rust coloured dust at the bottom of the carbs but all the jets looked clear and the banjo filters weren't that bad.

I'm still going to treat them to a complete rebuild just to be on the safe side. Just got to decide whether to go with the genuine Dellorto rebuild kit or a 3rd party one which is about 1/3 the price, but still sold on the Dellorto UK website so its got to be ok hasn't it?
