We know how to maintain gassers, not an issue. I still prefer diesel. A gasser that will start easy in Florida during the "winter" may not start as easy up here in the winter. Put a 3 cyl Perkins beside a gasser, and see which one starts better, which one performs better. (My Dad's 23c has not let us down.) Sucking in freezing cold air contributes to carb icing, even with gas line anti freeze, on the diesel they just keep going and going. Injector pumps have a longer life cycle than a carb, you just have to remember to add conditioner, with lube, example is the orange bottle of Kleen-flo, not the green, and now with ULSD you need it year round. Long gone are the days of straight methyl-hydrate, unless you freeze up, and even then you need lubes in the fuel.
Keep the diesel in a dry place, NEVER depend on conditioners being added by the fuel companies, and you will not have a problem.
