Throttle Linkage Question

[diesel don]

Our 1982 240D (w/ recent 300D turbo engine) has some throttle issues.

A few people have suggested that the linkage needs to be reworked upon transferring the turbo engine, but I can't find any specifics with the search function.

1. The piece on the passenger side of the IP is a bit sticky. I've used every lube known to man and can't seem to get it to function properly.

2. In addition, the pedal seems very, very inefficient.

We've put about 300 miles on since the conversion and this is the only remaining troubleshooting to do (with the exception of a better ratioed differential)

Thanks for any advice.
