Using rudder is about the only way to get most tail draggers off the ground, and that's what you'll have to learn do Killer Clam.

Seriously, it's just as FH described; hold full up and start advancing the throttle. Once the plane is rolling at a fast walking speed, relax the elevator to neutral and the tail will lift a bit. Once the plane gets to flying speed, a gentle application of up elevator will let it lift off the ground.

At some point shortly after the tail lifts, you'll probably have to start feeding in some right rudder. Just remember to go easy, on both the throttle and the rudder.

Good luck. It will come to you.
