Engine starting problems
If the pa28 has a separate starter button, then start on left mag only, then to both.
lycs don't have accel pumps if under 110hp.
If your gonna prime with throttle, make sure the prop is spinning before pumping throttle.
Cold start on 152 or warm, push primer as engine turns,
crack throttle, mix full rich, key in right hand, push primer with left, keep priming till she fires.
