1965 220SE No Start
Hi, a friend has a 1965 220SE Coupe that hadn't run in several years. Put in new plugs, points, cap, rotor, coil, OEM wires, cleaned the fuel tank. The car started, but ran rough and rich. Cleaned the cold start valve so it quit leaking fuel into the intake, it ran better, but not well. After setting the timing, it would idle ok, but not rev up. While I was checking the timing, my friend unscrewed the spring loaded knurled knob at the rear of the injector pump, the car died, and now it will only start sporadically, and run really rough, or not start at all, and when I pull the injector line, fuel just oozes out of the line, like there is no pressure. I pulled the fuel line to the cold start valve, and gas shoots out of there. It's acting like it's not getting fuel. What I can find about the injection says "NEVER" turn that knurled knob, my friend is like "oh it can't hurt anything". Well, it won't run now, and I can't find anything about resetting the position of that little knob. So how scr*wed are we, or is this something minor? I don't know much about this mechanical fuel injection, so any help, or a guide to a "Mercedes Fuel Injection for Dummies" page would be appreciated.
Update: I pulled the plugs, they were fouled black, replaced them with clean plugs, and the car started, setting the timing at 0 degrees, but the timing only advances about 5 degrees when I try to rev the car up, I understand it should go to 30 degrees at 3000 RPM? I pulled the distributor to send it to have tested. The car idles fairly well now, but I'm still wondering about that knurled knob on the back of the fuel pump. Distribtor numbers are 0281 185 008 JFU6. I can't find much information about this distributor, is this the correct distributor? Thanks in advanc.
