Hi, I have a 1984 280SE, and there is a problem when I am trying to start the vehicle. It take a long time for the engine to fire, and there is a strong smell of gas when I am cranking the motor. It seems to start fine when it is cold out, but if it is warm, it doesn't want to start. If anyone has some advice I could use, I would appreciate it.

Also, is this a European model? I have been searching for parts, but I'm having trouble locating them.

Thanks,
Joe
