Yes it does, I had a lapse of memory on that one. I haven't opened that part up yet, so I don't know how "tight" the fit is. The Datsun diesel pickup that I sold last winter also had one. I had noticed on that one that the throttle plate was very "poor" fitting in relation to what I've seen on gassers. I wouldn't have thought anythnig of not holding it open on a compression test, as it looked like the gap around the plate was too large to result in a restriction during cranking speeds.

Now for a correction - "MOST" diesels do not have throttle plates.
