My 1986 Seville starts and runs good while pulling tubes or whatever. Once I shut it down to swim or to let someone in the boat, it won’t start back up. Can take a couple hours before it will start again. It cranks but nothing. It’s just been retimed, and also there was a ground wire disconnected on the carburetor. Has fresh non ethanol fuel in it too. The plugs are white so it’s running lean. The temp gauge while pulling tubes is around 175. Previous owner had an electronic ignition installed. Please help. Thank you
