Thanks to Jin for a length of hose, but it seems my problems are not over. I thought the throttle spindle might be sticking so decided to fit my spare HIF44, using the the BBZ needle from the old carb, and treated it to new plugs. Once I remembered to re-connect the vac line to the Megajolt I got it to tick over at 900rpm and it drives nicely, except that at a small throttle opening eg. at 30mph in 4th it feels very jerky, which I can also feel on the overrun. The plugs are a touch darker than I would like, but the jet is adjusted as weak as it will go, and yes, I did remember which way to tweak it! The compressions are all over 170psi hot so no burnt valves and I sprayed Easy start to check for manifold leaks, even though it's a bit rich. This is a very irritating fault so please let me know if you have any bright ideas...
