accelerator cable adjustment

[shrig1969]

I have recently removed the carb for a clean up and this involved me removing the 2 bolts on the accelerator bracket.
Everything was re-installed and the van was given a long run yesterday. Unfortunately i now find that it is not as responsive on the throttle and regularly had my foot firmly against the floor.
Haynes is not very specific and there are varied online instructions which all seem confusing.
I cannot see any simple way of adjusting it in the engine bay.
I did read on here that you can gain access at the front via the offside indicator but don't want to open a can of worms if there is a simpler procedure to follow.
I am presuming that a slack cable would give these symptoms and it needs tightening ?

Seems an unusual coincidence that the prob with the throttle has only occurred since removing/replacing the carburettor? The speedo cable terminates at the wheel ( think nearside front , but not sure ) and fitting my new one went well - not a real expert but they normally fit ok I believe ( stand corrected if I am wrong).Could it be a carb issue?

Yep, there's only a nipple on the throttle end of the cable - replaced Vinnie's last year.  The adjustment is on the gas pedal itself, behind the o/s indicator.  Does seem an odd coincidence that its happened after removal.  Is it possible the cable outer on the throttle bracket has slipped rearwards?  That'd make the inner cable slacker without touching anything else.

Ok, just had another look at the mechanical workings of the accelerator cable next to the carb. The circlip was not quite in the correct position so corrected that. Also noticed when manually moving the throttle lever the cable and bellow bunches up between the bracket and the lever. Is this normal or is the cable pinching somewhere further back in the protective cover?
Won’t know for sure until I go for a drive later this week.

My terminology may have been vague. Throttle cable front to back not the speedo cable

Quick update…
Pretty sure I have a faulty accelerator cable due to my rough handling, when I unbolted it to remove the carb. I have adjusted it at the front and the pedal is much more responsive but I do get an intermittent over rev when I depress the clutch. If I hit the throttle pedal it settles down to a normal idle.
It must be catching somewhere so I’ve ordered a replacement to see if it solves the issue.

Afternoon all,
Today I fitted the new accelerator cable and went for a run. All was good until the engine got up to temperature and the niggling issue returned with the high revs at idle, tap the throttle and it drops again to normal. Returned home to investigate further......
With the engine running and foot on throttle pedal it would intermittently switch between steady idle and over revving. Checked around the carb and noticed it was sticking around the throttle linkage. There was a definite step/click when a little hand pressure was applied. Have tried cleaning around the spring mechanism, sprayed with carb cleaner but still the problem persists. 
I am struggling to understand the connection between the engine being hot and the carb throttle linkage sticking. 
Any help appreciated.
