Greyhound throttle linkage

[Acoc-06915]

I am a new member with a Greyhound.  My car has a cable from the throttle pedal to the carbs and I wonder is this normal.  I have a Bristol 400 which has a similar Bristol engine and the connection is with rods.  When I press the accelerator pedal there is an inch or so of movement before actually activating the carbs.  Any advice on where this apparent slack may be adjusted out as it makes driving in traffic more tricky.  Many thanks in advance.

Cable link is standard and will work as well as rods and levers. There should be an adjustment where the cable joins the throttle mechanism at the engine end. This takes up the slack and it sounds as if it needs screwing out so as to bear more against the outer cable. If you over do it the idle will get faster

Thank you for confirming that a cable linkage is standard.  So far I have replaced the return spring that runs from the shaft down to the bracket on the side of the engine and this has brought the idle to a steady 8 to 900rpm, still slightly high do you think?

I will now have a look and see if I can remove this initial play in pressing the pedal itself.

Its been many years since I've dealt with a throttle cable but it the cable housing properly seated on each end and is there slack in the cable (i.e. is it too long).

The adjustment on the carb linkage end should allow for the adjustment to assure the cable is tight.

I have identified the problem.  There was a tiny amount of slack at the ferrule at the pedal end and there was a spring fitted to the pedal (looked non standard?) which was holding the pedal back initially.  By simply removing this spring the pedal has no initial dead motion and the pedal response and feel is transformed.
