John, The fuel can only go 2 places since there is no return to the gas tank. One is the fuel can evaporate but that would take more than a few weeks. The second is that the fuel leaks into the engine. A likely reason is that over time the carb material itself gets porous or the gaskets shrink causing internal leaks. Since our carbs are decades old, porosity may well be the cause. I have the same problem in my "D" & my 66 GTO convertible.An electric fuel pump avoids the problem because it fills the fuel bowl before you try to start the vehicle.If porosity is the cause, I don't know if there is any solution. You could pour some gas into the carb throat before you start but I don't recommend it. I turn the motor over for about 5 seconds , pump the pedal about 8 times, & repeat this scenerio until the car starts. Not very scientific, but it works without burning the starter or draining the battery too much. If you find a better solution, let me know.

Hertog Sent: Tuesday, July 18, 2006 7:33 AM To: 'Chrysler300' Subject: [Chrysler300] two questions 1/ where can one purchase a brand new tinted windshield, of the straight (non-bubble) variety, as used on a 300G hardtop (other than Timo Tanskanen) 2/ what is the cause of - and the cure for - fuel "drainback" (other than installing an electric fuel pump) ? Some of my Mopars can sit for two, three weeks or more, and, after a couple of cranks, they fire right up. Some others, after sitting for 48 hours, need to be cranked for a LONG time in order to get fuel back up to the carburetor. There has to be a reason for this - any comments ?
