Just to clarify things......all you have fitted is the spring, spring guide and top hat supplied in the kit. You have not fitted any preload delrin washers, steel washers or the original piston weight/top hat. if this is the case then you should have no problems apart from being a little low on power. If it will not cock then you probably have the wrong spring.
