Carb setups have "personality". Each has it's own preferred starting procedure. Pump the gas. Once, twice. No throttle, hold the throttle a little, or halfway. Etc. EFI is touch nothing except the key. Light flipping on a light switch. That is nice enough in its place (wife's car, daily driver. work truck, etc) but I like that my antique hobby vehicles require some actual human interaction for proper operation and continued optimal performance. Modern cars are "hands off", old ones are "hands on". Not carved in stone, just how I like it.
