AAron, I have had this problem with a few cars. BMC used to oil the
cable of the Mini, every service, which meant, in our dusty climate,
they were always sticky, & "jerky".
On the 7 I find I have to do a good job of lubricating the throttle
pedal pivot, about once every two, or three years, to prevent the
worst effect. It starts to squeak when service is required.
However, with the cheep throttle cables we get today, there is
another problem. The 8 came with a cable which has an inner plastic
sheath, lining the steel outer. This never gets sticky, but I am
unable to find this quality cable in Queensland, or where the PO got
it down south.
My 7 suffers from a sticky throttle about every 3 or 4000 Km, with
its cheep unlined cable. Lubricating the throttle spindles, & the
cable with WD 40 will "fix" this for a couple of hundred Km only.
For a semi permenant fix I have to remove the outer cable, sliding
it off the carb end. I find it is always oily, from the carb end, to
some extent, & the oil has picked up dust. I clean the oiliness off
the inner, with a petrol soaked rag, & make sure it is thoroughly
dry.
I then wash out the outer with plenty of petrol, degreaser, & water,
blown dry, with air. After this I "puff" some graphite powder
through the thing with a squeeze bottle, & reinstall.
As I reinstall the thing, [for the 15Th or more time] I always make
the same idle threat, to put more effort into finding a good quality
cable for the old girl.

Ps. No my linkage, at 160,000Km is not loose, or sloppy, although
another 7s, I owned recently, was at less than 100,000 Km.
