[Healeys] Lubricant for SU carbs

[Bob Spidell]

White lithium is a good all-around lube.

However ... I suspect lubrication isn't the (whole) solution. Unless it 
has previously been 'restored' the problem may be with the bushings on 
the throttle cross-shaft located under the scuttle (assuming 6-cyl car). 
It came with brass/rubber bushings, which are likely shot. The solution 
is new teflon bushings and making sure the shaft is straight (it can get 
bent by R&Ring the engine). I did mine with the engine out, but I'm told 
it can be done in situ. With a straightened shaft and new nylon bushings 
my pedal was so smooth I though the throttle return springs were shot 
(they weren't). There is also a bearing on the shaft on the intake 
manifold, if worn it will add resistance.
