just dug out my set of 40's to give them a clean up before fitting them . One thing i noticed is when you open the up and if opening the throttle the butterfly's on the right hand pair go completely horizontal while the left hand ones the butterfly's don't open as far as the other side is this normal???

if they're still on the inlet manifold and joined together, chances are you just need to adjust the screw in the centre where they join to make them open up an equal amount. Either that, or the one that doesn't open as far has a bent throttle shaft.

when i've had another look , one side doesn't close fully but opens to horizintal , while the other side closes fully but doesn't open as far as the other side

[cossieglen]

needs adjusting on the centre screw where the carbs link then, adjust that either way until you get uniform opening on them

[Durham Fiesta]

is there any way to adjust the linkage arm as it needs to go further back?

[cossieglen]

Sounds like a bent throttle shaft then to me, if it doesn't close by going right back on the carb when it's on its own. If it's being held off by the adjustment screw then you're ok, but if it simply isn't returning to closed by itself then I'm afraid it sounds like you need a new throttle shaft for it.
