Hi everyone. I'm new to the site. I recently bought this truck 111,600 miles one owner,great shape . The guy replaced the head because it was broke. Ever since he put back together hasn't been able run correctly. I got it home finished hookin vaccum lines up, fresh battery. Wouldn't start.. dump fuel down carb, would fire up 2 seconds. Unhook fuel line from carb no fuel... is the fuel pump in the tank?
