This can happen if the nut on the throttle shaft is overtightened. I have found that backing it off 1/2 a turn or so helps

Also and apologies for this question. When you are looking down on the top of the carbs which way do you turn the jet nuts to weaken the mixture. Just want to make sure I get a base setting before thinking about needles/springs/oil etc.
If anyone wants a Vizarded HIF 44 let me know.

Weakening mixture is anticlockwise from the top.
Throttle shaft nut is a long, hexagonal nut on the inside of the carbs, that the linkage slots into. It should have a retaining washer with two spikes folded over the flats (this will obviously have to be bent up to release the nut).

problem is engine stalls everytime you stop. I'm wondering if it just needs a higher tickover. perhaps 1200 because of the flywheel and cam. seems a bit fuel wasteful but I'm not over bothered by that. Have i done something wrong? Any thoughts.
Perhaps go back to the HIF 44 LOL it doesn't look or sound as good but the performance is negligable.

Look for vacuum leaks on the manifold gasket or carb to manifold joints. Cutting out after blipping throttle can be a sign of air leaking in during high vacuum and overly weakening mixture.

The throttle linkage shaft between the carbs, at idle, must have some end float, ie, movement between the carbs. If it's at all tight, it will cause the butterfly to jam against the carb bodies as the buttery comes to the idle position (holding them open that little bit), where they need to be dead centre. Say 0.020" (0.5 mm) end float is well enough here.
