I drove my new Countach 4 days ago and it ran perfectly. I went to start it today, as usual I turned the key to the "on" position for 5-10 seconds to let the fuel pumps prime. I depressed the petal three times to give the carbs some fuel. When I tried to start it the car would crank and fire but it would then stumble for 10-15 seconds, it would not respond to input from the gas petal and it would eventually stall. It did this about a dozen times before I gave up and let it sit since I'm sure it was flooded (the whole garage stunk of unburnt fuel) by then. I went back after letting it sit for an hour and tried to start it again. This time I did not prime the carbs by depressing the petal. It would crank but not fire at all. I tried to start it about 5-6 times like this but it was the same story everytime. I let it sit for another hour and tried to start it the usual way and again it would crank but not fire.
