Hi,

In my (new) '78 300D I found that the throttle linkage doesn't return to idle because there's no spring.

It's a good thing I found this out before I got it started.

You don't want to hit throttle when it's running and have the motor run away due to a linkage problem.

So far I think the spring for this linkage is behind the IP down low somewhat like where a spring is on my '83 Turbo linkage (even though these linkages are very different).

Please let me know if I should look elsewhere because I can't find anything obvious where the spring went.

Thanks for any advice!
