I had my 1971 BMW 3.0cs running very well about 3-4 weeks ago. It's been sitting due to poor weather and some work I was doing on the car. When it was started yesterday, the car started up on the second try and ran to about 1800 rpm. I blipped the accelerator pedal and it dropped down to about 1100rpm. I then noticed this massive smell of gasoline and shut the car down immediately. Upon inspection, gasoline was literally everywhere: at the top of the carbs, in the base of the air cleaner, it ran down under the car and literally had poured out onto the floor. I did not notice where exactly the fuel was pouring from as I shut it down for safety reasons. For some background, the car had been running fine. I had been fully tuned and ran perfectly after being fully warmed up. The fuel filter, fuel lines are all new and there are no cracks in them. I am thinking that something is clogged, or the float is stuck, or ? but don't want to start taking things apart until I have a game plan.
Can I get a few thoughts from everyone on what could cause this massive flooding issue? Like I said, even when it was flooding onto the floor, it ran and was responsive to depressing the accelerator pedal but I don't want to start the car again until I've done some corrections before turning the car over. Thanks for any suggestions.
