Problem with a weber DTL twin choke on an Escort.. Runs fine whilst warming up and then when at normal temp it idles nicely but as soon as you try to pull away it dies. If you have the revs right up it just about makes it. Not being a carb expert would it mean the mixture is too weak? As in it'll run fine whilst the choke makes the mixture richer. And I can't find the mixture screw on the carb, anyone had any dealings with this sort of thing??
