Move the throttle linkage by hand and watch for proper return spring action
when you let go
You should have a return spring on each carb and a return spring on the
throttle linkage.
A friend had a similar problem and found the return spring missing from one
of his 2 rebuilt carbs.
If it isn't that, I'd remove air filters - stick finger in mouth of carb,
lift air valve with finger, make sure air valve drops quickly and firmly
down when you release it.
Hope this helps.

I recently installed professionally rebuilt ZS carbs on late TR6 engine.
I'm
having an issue I hope to get some advice on. After running at speed, say
2500 to 3000 rpm, and then coming to stop, the rpm is very slow to drop to
normal idle. I would say it takes about 10 seconds to settle down. The
problem is also evident when up shifiting, as the rpm stays high between
gears. I have inspected the linkage and don't find that it is hanging up
anywhere. Is it possible though that it could be something with the way I
reinstalled the linkage? Or could it be that the vacumn advance is not
functioning properly, or????
Looking forward to suggestions.
TIA
