Will the '68 Dart 225 run again?

Sorry we have not had a chance to check anything electrical yet, talked a a friend who has a mechanic relative, thought the carb may be gummed up and we actually are not getting fuel, may account for only running on choke cleaner. When the fuel was siphoned most of the 10 year old gas was gotten out, still may have been a gallon or two in the tank yet, so we added stabilizer and STP additive (red bottle) and put in a few gallons of fresh gas, we know the tank does have some sediment in it. The mechanic recommended cleaning the carb. Should we focus on the fuel system or stick with electrical? What would cause the car to be out of time if it just sat for years?

Sorry, I am a total :newb:
