I'm running a 28hp efi Super Z. I get so spoiled by the fuel capacity that I have ran it out of gas in one tank a few times before switching tanks. Everytime I do this it is such a PITA. It usually takes 10-15 minutes to get it running again, and thats if the battery doesn't die due to cranking it over. Its very annoying and somewhat embarrassing. Yeah I know I should just keep an eye on the fuel a little closer, but why is it so difficult to get running again?
