Did I kill it?

Guy

First time using egg today. Lit coals, closed lid to start low heat cooking. Temp shot up to about 500. I already put pork butt on, and wanted a temp around 250. To lower heat I closed all vents. It's about 275 now but no smoke at all. Could I have put coals out, and if so what now. 12 marines, and some friends will be here in 6 hours

Open it up and see if it restarts.  If necessary lift the cook and grill out and get restarted.  I kill the coals once in awhile when cool smoking salmon.

If your vents are completely shut the fire will go out. You need them at least opened a sliver. Keep an eye on it.

Be afraid.  Be VERY afraid.

Hopefully the Marines are also friends. Otherwise, you may be in trouble.
