I did bake the clutch at 210* for over 30 minutes and pour hot water on the spring last night. I did see the spring move ever so slightly, but to just turn it by hand to tell the difference isn't going to work. Centrifugal forces are a key factor for this I'm sure, hence needing higher rpms to really see if everything's working correctly. It was misleading having people tell you it's supposed to lock up completely and not freewheel whatsoever when it's engaged kinda threw me off at first but everything's alright now. I'll keep this thread updated once I get around to fabbing up a custom shroud.
