I've been working on Quadrajets since they first showed up. I was a mechanic before then. Over the years, I've put 'em on race engines.. I've put on F**ds.. I've put 'em on Mopars.. I've rebuilt probably a million of 'em (probably not, but is sure seems like it).. The Quadrajet is a well designed carburetor that works very well as designed and doesn't need any modifications, just the hands of somebody that knows how to make them work..

Let's look at this logically.. The "back flow" excuse is pure bunk.. Fuel cannot syphon from the carburetor back to anyplace.. Simple physics.. Only a few drops can make their way back through the need/seat, but certainly not enough to cause a no start problem.. The opening in the seat is above the fuel level and fuel cannot flow uphill.. IF your problem IS fuel loss from the reservoir, there are only 2 ways out.. One: evaporation... Two: leakage through the metering well plugs........
