Need to start damaged truck

I have an 1980, F250 truck which hit a cow... the front end, right fender, grill, radiator ,fan, etc was totaled. I am trying to start the truck. It is a 300, 6cyl and has been started by a friend since the wreck. (I did not hit the cow) I am selling the truck and need to show the prospective buyer it will run. The engine has been rebuilt and has less than 10,ooo miles on it.
How do I connect wires/remote starter to the thing to start it. I can make the engine turn over by jumping the solenoid but it wont start. I put fuel into the carb, the plugs were set at 50, but book said .44 so I reset them.
truck has been sitting for about 2 years, but started last year for a short period. still turns over, so not frozen... Any help will be appreciated since my friend who started it the first time is unavailable.

Thanks.

You most likely have a stuck float in the carbuerator. Tap the top of the carbuerator with the handle of a screw driver, and it should start. Don't hammer it, but hit it hard enough to jar the float. After two years of sitting I can almost guarantee that this is the problem.
