Re: [Chrysler300] Still Starts Then Dies - '65 300 Friday update

["Roger Schaaf" <obiwan10@xxxxxxxxxxx>]

When and after the engine stalls, how have you ascertained that ignition and 
timing are fine.  Seems if the engine is not running, it would be hard to 
have gained a snapshot of spark and timing condition.

I believe that you previously mentioned using another carb.  How about a 
plugged exhaust system?  I remember the old stunt to stuff a potato in a 
tailpipe, the victims car would start,  run a short time and stall. 
Although be odd to have dual exhaust both plugged.  Engine probably would 
continue to somewhat run on 4 cylinders even if one side was blocked.
