While a carb may seem simple it's anything but. When you have to track down what's causing that stumble at 3800RPM and finally give up out of frustration because of the pump cams, jets, squiters, vacuum springs, timing advance curves, vacuum pots, ect., ect.
Yep, carbs suck. So does messing around with fuel maps and other stuff the majority of these "performance" EFI systems need. Swearing at the carburetor that's dumping fuel out the exhaust is not a memory I care to re-live.
