Party $20-2: Top pair weak kicker in BB

[shoeman]

Early in a SNG, what is the line you would take if you flop top pair weak kicker from the Blinds. I generally check/fold the flop if somebody bets and lead the turn if it is checked around and no overcard falls. Is this too weak? Should I be leading this flop? And shutting down if I'm called?
