That's the weird thing carbs have been stripped down cleaned several times and now it's a 2nd set of carbs and still the same when miss
fires it tends to be cylinder 4 all the plugs seem to be ok. Everytime I work on it I always end up back at the carbs thinking I've done
something wrong when setting it up I.e the piping of it I've not adjusted the needle height but don't think that would cause the problem

Check you have a spark on cylinder four I would,could be a lead breaking down,or a coil pack.
The other thing worth checking if it is a spark issue there is a resistor in the end of the spark plug boot.
If you look up inside the spark plug boot where it clips onto spark plug you will see you can undo the brass holder with a flat screwdriver.
Unscrew it and check for corrosion and you can check resistor with a multimeter.
Another handy tool for setting up your idle fuel mixture is a digital thermometer, they are peanuts on ebay.
Use it to compare temps of the headers,this will give you a good indication of how the cylinders are working.

Going back to non turbo won't sort it!
As you have run it up with the plenum off so it was running non turbo then,just sucking air in through the carbs
