Thanks, chaps! I will have a closer look at the 76 fitted and see if redemption looks at all feasible. But I agree, trying to make a silk purse out of a sows ear can be frustrating. I persevered with the worn out 276 on the WDG3L for years (even trying a worn out 275 at one stage) and only got that fixed last year when I robbed the internals out of a newish stub fitting 276 that belonged to a project Sunbeam that went to a dealer (at a knockdown price, so no guilt felt!). But I learned a lot about carbs on the way, I guess! Main thing is......they wear out. Throw away!
The alternative is let Martyn Bratby have a look at it. He can make them better than new but you'll need a spare if you can't miss the carb for a while.
