[6pack] Left Hand turn stutter

[Sally or Dick Taylor]

Mike, and others---I know this low-fuel-level-in-the-tank is a popular explanation to why the engine appears to starve on left turns. I have a hard time buying into this. Even if the tank is temporarily not letting fuel get into the exit fitting at the bottom, what happened to all of the fuel that is in the lines, fuel pump and carb bowls? There should be plenty left to handle any sudden sharp turns. Assuming this turn didn't last for a duration for the cavitation to reach the engine.  For those perplexed enough to really find out if it's starvation or flooding, installing an O2 sensor and an air/fuel monitor (in the cockpit) would provide a clue.  
 
I love a mystery!

Dick

Just a wild shot here but how much gas did you have in the tank during your
maneuvers?  I had a similar problem with my TBI and discussed it with Rick
Patton who suggested that it was due to the fact that the gas line exits the
tank on the left side and there are no baffles in the tank.  Thus on hard left
hand turns when the tank is less than half full all of the gas goes to the
right side of the tank so there is no gasoline on the left side of the tank
for the pump to send to the carbs.  A little experimentation resulted in the
confirmation of Rick's theory.  YMMV.
