[Chrysler300] Engine trouble - still......... '65 300

["Ryan Hill" <ryan_hillc300@xxxxxxxxxxx>]

Several months ago I approached this listserve to try and solve a mysterious 
engine problem I was experiencing. Well, I've been busy with other things 
and haven't spent much time trying to figure out the problem until this past 
weekend. I'm still stumped!

Brand new, completely rebuilt 383 4BBl (AFB). Started right up and broke in 
the cam with no signs of trouble. Very responsive, ran smooth, everything 
normal. Car is not complete so I haven't driven it further than the end of 
my driveway. After running it for an hour or so over the course of a week, 
it started to run rough when warm. Seemed like it was flooding a bit. Very 
quickly it began running only when first started, then it would stall. 
(would run about 4-5 seconds max)

After replacing the fuel pump and no change, I replaced the carb with an old 
AFB I had laying around. It ran with the second carb leading me to believe 
my rebuild of the original was flawed. After a few days of running the car 
in the driveway to move it around the same symptoms returned. Now the car 
would only run shortly when lightly primed.

I've checked all the fuel lines for leaks, run the car directly from a 
gravity feed tank straight to the fuel pump, checked the vacuum (no leaks 
evident), the timing and dwell are right on, I've hotwired the car to rule 
out electrical problems, I've checked the float levels.......When the car 
starts up it runs smooth and fires right away but then stumbles and stalls. 
With the idle screw backed right off so the primaries are completely closed, 
it will start with no pumping (of the throttle) over and over. It starts, 
runs for a few seconds at low idle, then stalls. Any attempt at giving it 
some throttle stalls it immediately. I'm almost convinced it is flooding.

Does anyone have any bright ideas?
