starting help

50 years ago the car would have been driven all year long.

By any chance do you have rodants in your storage location?
yes and I seem to recall my mom getting her 66 Chevelle tuned up every 6 months. or she would say in late fall" time for points and plugs" anything to avoid that winter flood / no start situation. No on the rodents but its possible I see field mice outside every once in a while. I hear moth balls will keep them out of your car.
