My apologies, I wasn't paying attention to who posted . The compressor in the pic pushes on one side of the retainer. Not ideal but will probably work with low spring pressures. Flip the handle over from where it is in the photo and place on top of the valve. place fingers under coils and pull handle. You will have to adjust the bolt height to get proper amount of travel. refer to post #8 and others for more details, tips and opinions. Also if that tool proves to be completely uncooperative refer to post #2 for a picture of another type of tool as an option. Good luck.
