Clutch won't disengage! STUCK IN NEUTRAL!
I just got my engine back. Had it to the machine shop to get broken studs removed and new ones put in for the rear engine mount. When I got it back the clutch won't disengage, and it's making a grinding noise.
I took the clutch cover off and what I saw is in the attached images. The closeup image is with the spring removed.
Anyone know what's wrong? What parts I need? Also I looked at the inside of the clutch cover and it was all scraped up... it appears that the spring was rubbing against the cover. I don't know how the clutch works exactly so I don't know how to fix it. Any help will be greatly appreciated!
Thanks... I know SOMEONE here knows what to do!

there is a small screw that holds the "flower-nut" I can't see it in pics.

Yeah, that's it alright... it got stuck there under the engine somehow and i couldn't find it. Ehhh... it's been a long work week.
Now I have a few new problems.
1. What is the correct way it is supposed to go together? Does someone have an exploded image of the clutch so I could get it put back right and properly adjusted?
2. Where could I get a new star nut if it needs to be replaced?
Thanks for the help!

Here ya go:
The cases look a little different than yours, (because this is a new engine I'm making), but the clutch assembly is the same.

Re: Clutch won't disengage! STUCK IN NEUTRAL!
wow, thanks Jim... that was EXACTLY what I was looking for. You didn't just make that image up did you? You're pretty good if you did. Anyway got the clutch together and its working properly finally.
