If after a few km everything is good and is holding idle ok I would say that's normal. I find it takes a 3 or 4 km for the engine to be completly warmed up and to get a normal speed idle. Your temp guage may show normal but that is usually only the water temp. You can tell from the oil pressure. It is quite a while before the oil warms right up and pressure at idle drops right down.
Remember that the first half of the choke (on an su) is really only idle speed adjustment so just keep it out as long as is necessary until it idles ok with it in.
Thanks Phill, that sounds pretty much spot on what mine does. Do you find that even if the engine is warm after a drive and you turn the car off for a few mins and then fire it back up that it doesn't idle quite right for a little bit again for a couple km's?

Maybe still a bit rich and fouling the plugs?
I agree - if it's running a bit rich, it can misfire rhythmically and/or hunt for an idle speed.I changed the jet on my carb not long ago and put one that was too big in - it would drop to 400rpm and then rev up to 2000rpm and just jump between the two.
I did think it might be a fuelling issue. But if it is made any more lean it misfires a little with not quite enough fuel getting to the engine. As soon as it was changed back to this mixture setting the car ran much better
