you have to set the piston at bottom dead center not top, if it is at top the piston will travel to the bottom when you turn on the air and startle the sh****t out of you. make sure all the pushrods are out. and give the valve spring retainer a sharp tap at an angle to the valve to loosen the set that it takes after running a few thousand miles. don't let the air pressure fall while you have the spring off. you can buy the overcenter tool to compress the spring at any well stocked parts store they are sold for chevys but with some minor mods can be used on many other motors.
