1975 Mercedes 280C Firing Sequence
I think this will be a bigger problem than this but I just hope to have the car running again. Like the title states I have a 75 280C to which I was trying to give a quick tune up in the hope she would start up better. When I got her last October 09 she would start right up but then it became harder and harder and I have to give her constant gas for about 10 minutes for the engine to start going.
So I was trying to replace the spark plugs and wiring but in my haste and foolishness I forgot to mark the firing sequence on the distributor cap. I know the order since it's on the block but I don't know where the first value goes on the cap. However I have gathered that it runs clockwise starting from the first plug closet to radiator and going back.
I'm attaching a picture a of what I think is the right firing sequence.
Any and all help will be appreciated and thank you in advance.
