    Correct Idling Speed

    Hi,

    as mentioned in my other thread, I've to correct the idling speed. But looking in the different ROMs is showing different idling speeds:

    and in the German ROM:

    So, what is the correct idling speed for my 76' MK2?

    Regards

    I prefer to use the lowest idle speed that works. Too low and it can stall, especially if you have an auto. Too high wastes fuel, and if auto, makes the car jump fowards when engaging drive. Mines a manual and will idle at 450 but I use about 550.

    Another point is that if testing for emissions levels, a higher idle speed is sometimes used to get you through a test if you are marginal.

      My car which is an auto has adopted the German idling speed of 650 out of gear which drops to around 550 in.

            Thanks all for your suggestions. I will adjust it to 650 - 700 and will see, how smooth it will run.

              If it won't run smoothly at those revs, apart from the usual carb setting culprits, check your crankcase breather system has no leaks (the tickover should stumble/stop when you take the oil filler cap off if it is working properly).
              Header tanks - you can't beat a bit of bling.

                The pages from the ROM seem to relate to Mk1 stags only as later Mk2 UK and European Stags had a higher compression ratio. What would the recommended idling speed be for these later engines? I have searched but can find no Triumph published recommendation.

                    Thanks Good point should have gone out in the garage! However no-one else has referred to this label. Whilst it does not answer the OP's discrepancy between the German and UK ROM I assume it is more definitive. What does Badenstags label say?

                        I can't find this label on my car (assuming it should be under the bonnet). That's why I've referred to the ROMs.
