Time to Ditch The Edelbrock!

[747mopar]

The fueling issue isn't specific to a carb. It has to do with the Reed vaporization pressure of todays fuel. It's designed to evaporate quickly with temperature. Look at any new, vehicle all have closed loop venting and obviously, electric pumps. The cure is an electric pump and waiting a few seconds for the bowl to fill. Again, blaming a manufactuar for a faulty part on a used unit? Then missing detection during diagnosis. That is what's called learning. And I garantee you now know more about carbs than before. That's a good thing.

I've put this off long enough liking the simplicity of mechanical pumps but it's become clear that unless I want the continued embarrassment of a stubborn motor something has to change. I'll be switching over to an electric fuel pump and return style regulator this summer. Better cure it!
