Hi all, I am brand new to this forum and antique Hondas. I bought a CA77-E from 1963 and it has been barn kept it's whole life. Unfortunately, the last person to own it did some real Mickey-Mouse fixes and basically stripped half the screws :(
I've never disassembled and rebuilt a motor in my life, but I just moved from NYC to California and have a big garage to fix things in so I'm so happy to have the time and space to give this breakdown a try. One thing I initially noticed was there is something messed up with the clutch plate slipping, if anyone has any help they might be able to lend me, here are some photos of what I mean.

Secondly, and I think, more importantly, is this piece I can't quite identify. The metal around it looks pretty gnarly and I can't quite figure out (even with Bill Silver's rebuild instructions) and I also can't figure out how it got gnarled in the first place. Here's some photos as well.

Again, thank you all so much for any help you can lend.

Clutch Disk Issue
In the first set of images, it looks like the clutch is missing a plate between two of the friction discs. It looks like the clutch basket is rubbing on the inside of the left engine cover, as well.
The second item is the lock nut for the primary drive sprocket. The "gnarly" part is the locking tab washer that has a tab bent up to lock the nut in place. If you remove it, bend the tab back out flat and remove the nut. There is a tool to remove the nut, or you can spin it off with a well placed chisel. When you replace it, be sure to use a new locking tab washer.
Re: Clutch Disk IssueFrom what I can tell the clutch parts are not installed correctly and you have 5 currect plates and one OLD DESIGN. (get rid of it.
The nut is installed wrong side out. Please cann after 5 your time as I have questions to ask when you are at the engine. 830-895-0654. ...................lm
