hold the elevator down whilst takiing to prevent it nosing-over (not so important on tarmac but good practice) and throttle up smoothly with the elevator still down but release elevator as you build up to takeoff speed
Foamy,
If you hold DOWN elevator in while on the ground this will actually lift the tail of the aircraft and put the prop into the runway. You need to hold UP elevator while taxiing a taildragger to keep the tail on the ground, and release this when you start to accelerate for take-off.
