Bought 1976 evinrude and had to replace starter solenoid to get it to start. ran it on muffs at the house to test and it ren ok. got it to the water and had to use manual choke to get it to start. finally got it started and out on the water. ran for about 5-10 mins on full tank of gas. It used up all the gas 18 gals and died. tried to restart but have not had any luck since. have checked for spark and not getting any, tested all wiring and don't seem to be getting any spark at all. confused on why no spark after running out of fuel. HELP!!!
