That may be what they recommend, but I've never found it to be the case. In general, every owner will rather quickly find the starting process that works best with his car. I generally give it a bit of throttle just to keep it from dying once it starts. > Could it be in your case that the cold starting valve or thermo switch is > acting up? or perhaps all you need to do is hold the pedal to the metal > during cranking without releasing until the engine fires? It's possible, but the temp switches were pretty reliable. I've never seen a bad one. Unfortunately, the cold start valve, etc. is just about the first thing that gets blamed in cases like this, but real progress toward a solution usually only comes when we look elsewhere. Still, it's worth considering. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
