Closest thing I have is some new 13682 / 141D806 / 141-0806 . My literature doesn't have a spec sheet for the 13817 (your carb) so I'm not sure how many differences there are. I'm pretty sure the choke is different, but not sure past that. Zenith doesn't show a direct replacement number, not sure if Onan does or not as my literature from them is slim. If you're interested you can email, don't want to use this post as a sales ad.
