I have owned a Daimler DS420 1981 for some time now (about 10yrs) and the car has always been hard to start and runs rich. Countless mechanical services and plug changes, (by a long time jag trained mechanic) plus always need to warm up the car for long periods of time. I changed mechanics a few years ago and he asked why the AED was put on back to front? No wonder you have choke and running issues. He corrected, and the start up changed enormously.
The car has been sitting for awhile and at rego time the car wouldnāt start for a number of reasons. Carbs were completely serviced as they were clogged with fuel gum etc. new serviceable parts installed etc. The car however, was still not running correctly. Reluctantly, he suggested the AED will need servicing. The unit was pulled apart, new diaphragm ordered as other was hard and dried out. He has mentioned there are parts missing and asked why, which I just shrugged.
Looking at the following link;

See parts 21,22 and 23.
Can anyone advise why these would be missing? If essential, where can I obtain, as these are not serviceable parts. Iām sure he want wants to install just to see if it improves start up and decreases the number of time the plugs are changed.
Cheers
Mark
