I keep having a problem with this linkage coming apart from turning the throttle. I have looked at the parts diagram and don't see anything missing. The pin just keeps popping out for some reason. I would think there would be some sort of pin that goes underneath to hold it together. What am I missing?

Looks to me like the gape of the spring has opened up a little. Can't cost much to replace the spring.
 
I can't see from your pic. Am I correct in assuming that pin isn't long enough that it has a place where it goes all the way through and an e-clip holds it in?
 
It looks like this part. In which case the pin was a press fit when it was manufactured...

If it was me I'd find the right size bolt and nut.... Put some permanent locktite on the threads and tighten it just enough to be firm and not bind the spring.
 
If that is the case then the best thing to do short of replacing the whole assembly is take a center punch and peen the base it goes in and create some interference for the pin. Then clean the pin and the base good with brake cleaner. Loctite makes an epoxy called Press Fit Repair it is made for setting bearings and other press fit applications. Coat the pin and the base and press it in, you can probably accomplish this with a C-clamp or a big pair of channel locks, and let it set up good. I doubt you ever have it come out again.

Sounds like a good idea. Another would be to remove the shaft-lever, tap a small bolt into the bottom of the pin, and bolt it together with a washer and red Loctite, reinstall the shaft-lever. Save 115.00 if you could find one.

This is the exact same set up on my 1994 20HP, and it is definitely a press/pein fit.
 
Decided to post a follow up here in case anyone else has this issue. I used some Permatex sleeve retainer that I found at NAPA. It's used for press fit applications. After a full season of running, it hasn't moved. Worked very well.
