i am doing work on a friends 84 lude carborated model *pardon my spelling * and i need some help the problem is the car WILL NOT start or run without ether being shot into the carb once it runs out of ether it dies now i know this is a fuel problem but he said he already changed the fuel pump and fuel filter so i know its something wrong with the carborator so wat else could it be wat do i need to check for he said last time he drove it nothing out of the ordinary was wrong could it maybe be a cut fuel line?
