Well, that is a beautiful rig, and I love the 58 Bigtwin. It is possible that the stalling is being caused by something else and the spilled fuel is just a result of the engine sneezing/sputtering when it stalls out…
Is this the only issue with the engine, does it idle OK, run at high speeds OK? How fast are you retarding the throttle? Will the engine keep running if you retard the throttle very slowly? Are you running the engine with the big air box in place, or is it removed?
There is also a possibility that the vacuum cut out switch is malfunctioning causing the engine to stall because it is running on one cylinder….
Is this engine new to you, or did you do some recent service work to it? You mention making some mixture adjustments, what do you mean by "repairing the fuel filter"? Is the engine still using it’s original pressure tank set up, or has someone converted it to a single line tank with a fuel pump?
If the engine is actually flooding over, then it is time to pull the carb apart, and install a new OEM carb kit that will include a new float and float valve….
