    By the serial number it looks like a miller made for airco welder.
    Go the miller's web site and look at the roughneck welders.
    Also send your question to duaneb55 By private message. He is good with these old welders.

    Check the ignition points for corrosion or damage, Got a Harbor freight near you, not their biggest fan but they have an inexpensive tool that goes in line between the wire and the spark plug that will show a flash when you crank the engine if it is getting spark. Also I believe a bad condensor can kill the spark. May have bad spark plug wire as well. I would look into the points first. Don't remember about the CCK but on my Onan B43E the points are under a little box cover top of the motor behind the carb. Find the ignition coil and trace the power wire back to the points. Onanparts is a member here and is the guy to talk Onan to.

    If you mean the engine has no spark I would change the condensor and check the points. Over the years, the onan engines I have been around go thorugh a condensor every couple of years. If no spark at the electorde I can't help as much as others on here.
