noon rebuild question

[spiffy926]

Actually I had forgot to hook 12v lead to the glow plugs rail... so the contact was just barely resting, but not attached. I tried it today with the glow plugs hooked up and it started much quicker, like 10 or so revs, but I did need to give it a little throttle to get it to "catch" when it was almost there. What are the revs supposed to be for a cold start? It idles at around 900-1k cold, and it's steady at 800-900 warm. Maybe the cold start device is misadjusted?
