Modern fuel is what makes a carbureted system difficult to tune and maintain. Up to 10% ethanol means every fill up will be different. It lights off at the drop of a hat and the ethanol draws water. Letting the carb sit for long periods causes the bowls to dry up and leave residues behind. EFI can eliminate for all these issues. Sure a electric fuel pump can help a carb system but it doesn't adjust for fuel differences, changes in weather and/or altitude. But I have a carb. Someday I may switch.
You will see out of the box failures on any product. Be it EFI or Carburation down to underwear. It is going to happen. Buy what you are comfortable with tuning wise, know the pluses and minuses of each and install both correctly.
