    Looking at the air box covers, I'd say you have a 3-71.

    thanks guys, still haven't gotten it fired up... like i said, when i pull the fuel rod out it'll smoke enough to...kill all insects within a 15ft radius, but beyond that doesn't even sound like it's trying, thinking i should get some fresh diesel... if that doesn't do it, perhaps a sticking injector? i did pull the valve cover (it is EXTREMELY CLEAN) and everything is free, nothing is stuck, i'm amazed by how clean it it... i made sure all the lines were tight to the injectors.

    Oregondiesele,
    There is a emergency shut off on Detroit Diesel engines. It is spring loaded and will snap shut and shut off the air supply. That is something that is easy to miss if you are not familiar with DDs. Also fresh fuel and fuel filters are a good starting place.
    Good Luck

    Looks more like that silver solinoid to the left of the blower is attached to the shutoff flap. Is it moving when power is appied?

    it doesn't move, it is stuck in the Down position, i've tried it in both the up and down positions with no luck (either way it just smokes up the yard)

    The silver solenoid attached to the blower inlet housing is an emergency air shut off. Make sure the little reset lever on the bottom of the trip is down. That will let air to the blower. Make sure you prime the fuel system good. You should have fuel coming out the return line from the head. Disconnect the fuel line at the output of the fuel pump and prime it there. It should start. Diesels don't like air in the fuel system. You might also want to check valve clearance and injector timing later. Have fun.

    i did a no-no today, and ran it on some ether, it fired right up, and just needed a trickle at low rpm's, and ran on it's own at higher rpm's but smokes like a mother....
