accelerator linkage

Postby Barry153 » Wed May 06, 2015 10:46 am

Hello All,
I have 1964 Mk2 3.8, I am having problems with the accelerator linkage sticking and not allowing the engine to tickover at 750 RPM.
It sticks at 1000 RPM until I blip the pedal and it returns to 750 RPM until the next time.
I have dosed the linkage with de greaser and then lubricated it as far as is possible without dismantling every thing.
Has anyone attempted to replace linkage with a cable?
I would welcome any thoughts.
Thanks
Barry.

Barry, I have a 1961 Mk2 and the linkage got a bit sticky and I found that just lubricating it did not do the job. I found that I had to take it apart (assuming it is not the cable itself that is dry) and clean the joints, especially the little ball ones which were a bit caked/rusty looking. After re-assembly I found it then worked fine.

Thanks Paul,
Forgive my ignorance but I can't see a cable on my car, it appears to be rods all the way from the carb linkage to the pedal! Where is the cable?
I have bought a new return spring so I will see if that helps.
Regards,
Barry.

There should be two springs to close the throttles, one on a lever on the throttle spindle and one from the link to the spindle (on early cars).

Apologies, of course it is a linkage running across the bulkhead and then to the carbs. I did the bonnet release at the same time as that was sticking so the picture of that was in my mind. I will have to put it down to old age!

Hi Barry,
I have the same problem, ticking over at 1500 until I blip the throttle. I put a little oil on the joints in the linkage that were easy to get too in the hope that that would do the trick.
It is a little better but not sorted so it looks like a full strip down.
Is it a difficult job? Space looks quite tight down that side of the engine and the linkage looks a lot more complex than it needs to be. Is it as difficult as it looks? Any tips?

Thanks
Dave
