I have a 1976 25 HP electric start or pull start Evinrude that starts up great and runs good at idle and soon as you give it any gas it immediately dies. It is an electric start model but not using any of the controls. Carb is clean, choke is working properly and slow speed needle looks like it is at the correct setting but I am wondering if any of the electric controls could have anything to do with it. I don't have any of the controls or wiring. Any help is appreciated.
