i just bought a i think 1976 b6000 it won't start unless u spray with starting fluid which i know is wrong with glow plugs can i test them with test light to see if they are getting current how do i test them otherwise do u just take wire off and unscrew plug and re install new ones... when it runs it blows clear and sounds good even though i think there may be a lot of hours on it.i hope it's not the injection pump. the original fuel filter is not on the machine and a inline is on it.. also is there a place for used parts like hood steering wheel etc thanks azjim
