My 1992 60 hp Evinrude motor won't idle. It will start and run for about 5 seconds and then shuts down. I have to operate the choke to keep it running. Also it will run at high speed but falls off after a few seconds. I can't shift to forward as it goes dead. I have rebuilt the carbs, changed fuel line (tank to motor) used new portable gas tank with new line all with no help.
Thanks
