Help please! Engine not turning all of the sudden..., Car was running, died, and now won't turn over. Options

[nick73-914]

New owner of a '73 914 1.7 here:

I've been driving her three days now, no problems at all except the idle was a little slower than desirable (dying at stop signs/lights etc.) But the engine is running oh-so strong (IMG:style_emoticons/default/biggrin.gif) . I tried adjusting the decelerator screw by the throttle, opening it up to speed up the idle and also adjusted the knob on the pressure regulator bracket by the battery, after initial adjustment it was idling PERFECTLY, nice speed and depth. I took her out for a spin down the block, pulled into a driveway to turn around and the idle got slow and it died before I could put it in reverse.. no big deal right? well I turned off the key, engaged clutch and tried to start, nothing.. no turning or anything, the battery is two days old so it's not that and the door ajar buzzer came on, along with my hazards.. Any help here form you 914 masters to a youngin? Much appreciated!

Thanks
