what are the spring rates on a orange yellow orange primary spring? Got one in my Ulmer clutch kit and curious how it compares to the one I took out. My manual doesn't show that spring on the chart.

You sure it isn't orange-pink-orange? That's what was in one of my old kits.

The sheet he sent with the kit had o-y-o on it. I've tried calling and emailing him no replay.

Thanks for the information. The old spring was a EPI with the following spring rates below. I'm new to clutching trying to figure out what does what and what the differences are. It also had 84g weights. My Ulmer kit has 60g with some washers added.
