But, the inlet to the carb is at the highest point on the carb. Anti-gravity petrol? It just doesn’t seem possible. It couldn’t maybe slowly drain into the cylinders, could it? But if it did that, it should drain out the line on the intake but it doesn’t do that since there’s no pool of petrol on the ground and if they did do that, wouldn’t Tractions be known for it? if I drive mine every day they start instantly with no pumping of the lever, more than a day of sitting, then I have to. The fuel can’t possibly evaporate that fast. I’ve been home recently recovering from surgery so I have time to ponder such an imponderable.

Possible answer for you Larry. My mechanic was doing a bit of work on my carb and he noted the main jet is just sitting in the tube from the float. So, fuel could leak out the joint until it reached that level, making for very hard starts. The fuel would leak through the drain in the intake manifold. In my car it was leaking quickly enough that the fuel spill was visible, but perhaps if the leak was slow enough you would only have a very small spot? Regardless, a little sealant at the joint and the car starts on the first pull even after sitting 48 hours.
