Here is the story. I bought this 1990 300SE for parts that I want to swap into my 300SD and later part the rest of the car out. It has hail damage, some sort of car accident on the passenger rear quarter panel, the paint is terrible and the front end is shot to hades. Since I will eventually sell the engine and possibly transmission, I would like to get the engine to start and run better. It will eventually start cold on its own but I have to crank it several times and way too long. The PO used starter fluid to get it going quicker and that seems to work. Once started, it runs rough until it warms up. While driving the car, I noticed that it is very low on power. It barely wants to get out of its own way even if you have the accelerator to the floor.

Since I don't want to put any money into this car, I am asking if there is an adjustment or something simple I can do to get this engine to start and run better for the sake of selling it. I believe the engine is good because I don't hear any knocking or tapping, etc and it idles like a sewing machine once it gets warm and runs for a while. The fluids look good as well.

Thanks for any suggestions.
