I have a 1976 Johnson 55 Hp with starting issues. Some times when I go to start it, It cranks very slow like the battery is dead and the next time I turn the key it cranks fine, First thought was the battery and connections, I cleaned the terminals and charged the battery that wasn’t it, so I changed out the starter that wasn’t it either, My compression is 110 pounds on each cylinder any help would be greatly appreciated Thanks TJ
