It sounds like you are describing the pin that operates the float vent valve
on later TR6.  It is supposed to be spring-loaded, so pushing on the pin
doesn't hold the throttle open.  But when the vacuum retard is disabled,
sometimes the pin bottoms out before the throttle is closed far enough.
Should be an adjustment somewhere for how far the pin gets pushed.

There are some pictures and a description in the article at

However, my early Stag has a different arrangement (which I think maybe was
also used on some TR6), so your car may not look exactly the same.  Although
there is an adjustment screw for the pin on my carbs, I had to bend a clip
in the linkage to get the throttle to close.
