1990 GMC C2500 Two Wheel Drive 207000 miles

I just bought the truck from a friend. It ran great before it sat for about a year and a half. It is now hard to start and is backfiring out the carb. The distributer is tight and doesn't move. It has very little gas in it and it is old. Where do you recomend that I start to fix the problem.

Fresh gas, Stablizer, Heet and then SeaFoam to clean fuel system. Once running Oil and filter, flush coolant, fuel filter and check plugs and cap.
