No cold start valve spray
Hello Gentlemen
Just bought a 1987 560 SL. Love it. When cold it takes a long periods of cranking to finally run. Then it has a rough idle and ABS light is on too. When driving and specially on the freeway it runs beautifully. As soon as comping to a stop it starts running rough again.
I pulled the cold start valve and cranked the engine and there was no spray. Tried the same thing in my brothers 1980 450 SL and we had nice spray of fuel and the engine starts right up.
Any ideas?
