Interesting...

What is the mechanism that causes dual direction fuel metering with the Webers, and not with the 8-stack EFI?


The carbs keep a constant cloud of atomized fuel in suspension in the carb throat. The fuel injection doesn't. It squirts a timed amount of fuel into the throat of the intake manifold.

When the reversion wave pushes back, there is no cloud of fuel to be pushed out.


Thanks Doug, that makes perfect sense...
