putting my mach z up for the summer i took my secondary apart and found one of the buttons have broken off. this happened once before during the winter when i was cleaning the clutchs. i`m running a blue goodwin spring on it and it was set at c6 i`m not sure if the preload was to heavy and putting alot of pressure on the buttons. i put it back together setting it up on c1 to take some pressure off.what do you guys think?......thanks

I don't think C-6 should be too tight (usually around 17-19 lbs. for that position). How often do you check or clean your secondary, and does your cam have any rough spots or nicks in it on the ramp part ? You can take small scratches out with 320 wet/dry sandpaper then buff with 1000 grit, but only if it's a steel or aluminum cam and not a teflon coated one (whick I would replace if badly scratched).
Hope this helps !
