MF 1235 Black Smoke when Starting

[gflitter]

My MF 1235 with 450 hours will not start without using the glow plugs and it just pours out black smoke when I try to start without the glow plugs. It runs well and does not smoke much at all once it is started. I have new air filters installed, so that is not it, and I understand that the black smoke is unburned fuel, but I do not understand why it doesn't smoke much once started. Can anyone tell me why it does this?/forums/images/graemlins/confused.gif

gflitter, My 1235 manual instructs me to always use the glow plugs to start the engine. I always get a little black smoke at initial start up............................................BER
