  • Miller 200le need help

    I just bought a 200le and the guy told me it ran and welded so I went home and hooked jumper cables to the ground and starter and could only get it to turn partially over so I manually tried to turn the engine over and it will go about half way with ease and then hits a hard spot and will not turn anymore you can turn it the other way with ease untill it comes around to the same spot and it will not go any further any suggestions would be appreciated by the way it's an Onan. Thanks

    Take the plugs out and try to turn it through the bad spot.

      Take it back? You should of had him demo it or tried it yourself.

        Miller 200le need help

        Well I payed very little for it and I can scrap it and make more then I have in it. I think I can make something of it. I was just looking for some advise I'm very mechanically inclined I just didn't know if I had enough battery current going to it ( like if there is a safety ) in it not allowing it to turn

          ​like they said take the plugs out and turn by hand if it does turn good you may have to set the valves to spec that's where I would start.

            It could be a broking connecting rod for one of the pistons. But if you didn't pay much for it might be worth fixing. I have a AEAD 200LE its 40 years old and runs very good. Good luck!

              Definetly agreed. I have a newer bobcat 250, a Lincoln sa200 and my aead. My aead is my go to machine. Love the bead that thing burns. And does well with gouging 3/16 copper clad rods. I would definetly fix it if its not more than around 1500 parts
