My 74 Spider cranks a lot on a cold start before it starts up. I am checking with the forum in order to find out what it is. You guys are the experts!? I was told by the guy at the shop that it is probably the fuel injection primer. Where exactly is that part located and where would I be able to find it. He said it was an easy job and it was just a couple screws that need to be removed when replacing the primer. Thanks in advance!
