[Healeys] Throttle? linkage

[Michael Salter]

I have run into a similar problem when the butterfly is loose in the
throttle shaft. It will slip slightly out of place while the throttle is
open then prevent the throttle from closing completely when the pedal is
lifted. 
Blipping the throttle will often make it relocate to its correct position.

My BN6 with HD6's idles just fine at around 800 rpm and the mixture is
correct as far as I can determine. Problem is that when I accelerate the
linkage sticks coming down at about 2,000 rpm and stays there. When in the
cockpit, trying to raise the pedal with my foot does nothing -- it is
already up as far as it will go.

Under the bonnet, when I goose the linkage by moving the relay shaft to
carbs, it comes right down where it should at 800 even running past 2,000
rpm. If I hold this shaft open above 2,000 rpms, it will only come back down
to 2,000 rpm and I have to nudge the shaft to bring it back to 800.

What am I missing???
