I have an '87 643 that is a great starter since I replaced the glow plugs last year, but has been struggling with power loss under most conditions. I felt like it was missing on one cylinder so I finally got around to replacing the injectors (from fridayparts.com) and once I put everything back together and bled the fuel lines and got it started, the exhaust was just straight black smoke. After a minute or so, I didn't have any throttle control and it was idling up and down slowly on its own. I actually couldn't kill the engine with the shutoff knob and had to close the valve on the fuel line to eventually kill it.
Is there something I don't know about aftermarket injectors? Any insight is greatly appreciated.
