Item 36 is indeed identified as a cotter, however that item is located at the BOTTOM of the shaft.
The description for the cotter pin in the IPC says "(Attach Handle and Shaft Assembly)" and the quantity is 2

That might be a revision issue. My Sept 1, 1956 electronic version does not state that and indicates only one cotter. (I'd post a copy but I haven't yet figured out how to do that in this &^%#^%# Windows 8 new laptop.)
In any case, we've all learned the IPC is not an approved doc and has many errors (tho' I'm not suggesting that in this case.) The IPCs should not be used for assembly-guidance except as a last-resource, especially as regards this fuel valve.

The revision I am referencing has an 11-58 date on the revision page.
Early 48 Fuel Valve.pdf
If there is a revision out there that has different information, I would really appreciate seeing it. Perhaps you can you post it in the Mx section.
Also if there is any other data that you are aware of with these details, that would also be appreciated.
Thx,
Dan

Dan, that page is a revision page, not the published date of the IPC.
In any case, I wouldn't be worried about whether or not it was a roll pin or a cotter. Either would work. I was just wishing to mention the use of safety wire when a roll pin is found or used.
Also, re-reading this thread I see why this mention has become the focus. It is because of my prior post in which I failed to also mention that some valves have the lever secured with a screw rather than either pin or cotter. There clearly are differences in the field. (Perhaps due to change of sources for parts.)

George:
Thanks for the clarification and please tell me where to find the published date so I can make sure I am referencing the latest IPC.
I have 3 or 4 IPC's for the 48 at home in hard copy and will also review them.
I went thru what I have saved electronically for the 170, A, and B and they are all showing the cotter pin. However, the 170B shows pictures of 2 but only calls out 1.
I appreciate your help,
Dan

The issue date is on the Title page, but any revision pages should indicate incorporated updates.
As for the "latest" version... forgettaboutit.... Cessna quit revising the document years ago. It has only catalog status anyway.
