I happened to find this little gem online & wanted to make it available to members for reference. It's the original 20R Engine Service Manual. You can view it online a page at a time, or you can download manual sections as PDF files to save on your computer for offline viewing. There doesn't seem to be a single download link for the whole manual at once though. Here's the link:

Just a great source of original factory info I wanted to share.

 

Thanks! I combined these into a single PDF and uploaded to gdrive in case anyone needs it - https://drive.google.com/file/d/1tZD...ew?usp=sharing

 

Thanks 13Swords and wallyworld!!!!! I don't have a 20R currently but I do have friends who have them and I imagine I will have one someday. This will be super helpful.

Y'all are awesome,

Sam
