description was perfect, although I had one problem when they ship it, they installed the screws in the grooves of the airfins that provide cooling and it got all scratched up and **** **** I was very unhappy about that and because of the scratches I'm not going to use this for what I thought. Instead I'm going to save it as a backup in the event I need to replace the jug in piston.
