You can also use Lubriplate 105 in the lower unit. Make sure you replace the impeller. At worst it will have taken a set and not pick up water very well but could have blades break off and plug up the water jacket if you try to start it. I have seen both cases with old outboards. I would recommend replacing the float or coat it with fuel proof airplane dope. Clean the carb and fuel tank well usually a lot of crud in the tank sometimes hides in the front of the tank out of site. Run fuel at @24:1 ethanol free if you can find it. May get lucky with the coils but if they are cracked replace them.
