Bruce, Bear with me - I am no expert, let alone SU-savvy! I had previously taken the floats off. My original fuel pump was dead, but I didn't realize it at the time. I took the floats off to see if any gas was getting to the carbs. There wasn't any, and I must have used too much force putting the floats back in. I am talking about the "arms" that suspend the float - there is a central tab that closes a valve that I assume suspends fuel flow until the gas level in the bowl recedes. These arms were bent, so much so that the central tab was not even making contact with the valve. When I bent the float arms back to a point where the central tab touched (and actuated) the valve, the car worked perfectly. So, originally, after installing the new fuel pump, the car was spurting fuel from the overflow tubes that exit the back of the air cleaner. Coming out quite a bit too - that caused the pooling on my drive way. As I said, once I fixed the floats, this stopped immediately. I do agree with you that a fuel pump would have little to do with starting - but my guess is that the original fuel pump wasn't doing much, effectively leaning out the mixture. I can say this, the car hasn't run this well since I've owned it. Only things I changed were the fuel pump and the correction of said bent floats. My apologies for the terminology - I don't know the SU carb as well as I should, but all seems to be ok now.
