Larry:

I have driven my 83 300D for years before a figured out how to adjust the vacuum control valve and stop the engine flare from 2-3 shift.

I had very bad cold engine performance: smoke and rough idle. It would improve as it warmed up. Did the drip test and got fast drips. I could not adjust it to "one drip per second" at 24 BDTC. Removed the IP (about three hours + and a big mess) and found the notch was a few teeth off. Set the IP, and reinstalled. I was able to adjust the timing to the "one drip per second" and found a great improvement.

I can't believe I driven this car with those problems for so long. Now, I can really enjoy the car. These repairs were made with no $$ (except the IP gasket) thanks to this forum.
