Without the magneto and flywheel , I am not sure that is such a great deal. What did this rebuild entail? From the pictures posted, it looks like it could have just been cleaned up on the outside and hit with a quick rattle can paint job. I sent him a message asking for more info, but I didn't get a response. To me, that is a red flag. At $500, I would be willing to take a chance, but not at $1000.
