Six months isn't really very long for an engine to sit. I usually just start it up!
Typically, I have to charge the battery first, but you get the idea.
If the car has sat for a year or two (and yes, I have let cars sit that long before) I pull the coil wire and crank the engine for ten seconds at a time, resting five seconds between cranks. I do this until I either see the oil pressure coming up, or ten or twelve times (in other words, until I get impatient).
Then I connect the coil wire, pump it three times, and fire it up.
So far, this hasn't done any damage (that I know of) and it's a lot easier than pulling the dizzy to prime the pump.
