Need help first Yamaha Chappy no spark how to set points. Don't have a manual. Thanks

Hi steve", you need feeler gauge -and the correct Gap,  as your timing is set this way too, . member "Wild foamy]  on here has a chappy,

and info, 

I got a gauge but no idea on how to set the timing. I work on Honda Z50s but, I don't see any marking on the flywheel to set them. I have no info on how to work on a Yamaha. Thanks

Eh all I got is a parts catalog for mine, I can measure mine up when I'm back at work if that's any good to you?
