In general, this does not affect carbs at all, but I suppose if you had an extreme case it might keep the chokes from opening completely, which would make the engine continue to run rich. You should be able to check this at a glance, however, by just looking at the chokes. > My VR is still clicking away (I haven't measured the voltage) mostly only at > high revs and not continuosly (i.e. It goes for a bout 2 - 3 minutes and then tt > stops. Then it starts again after 5 minutes or so) If your VR is clicking like this it would be a good idea to go ahead and replace it anyway. You need a Bosch 30 019. It will also keep your battery in better condition. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
