Trophy Need Fuel Pipe Help

Hello again, after alot of problems getting my starter motor to turn, I did it, but now I'm abit confused to why its turning over but not fireing up, I have 6 pipes in total, a small one opposite side to the fuel tap, then I have 4 bigger ones coming from the carbs, and a small one coming from the carbs aswell, I only have two big holes on either side of the fuel tap and one small hole in the centre of the fuel tap, does anyone know witch ones go where and why I have two extra pipes coming off the carbs thanks.
