It is me or do engine builders put the recoil on upside down?
I'm guessing you didn't build this engine. I'll bet you bought it from Uncle Frank. My clues are no stickers on it, then Uncle Frank stickers on it sitting on a minibike. First picture, it is on a checkered tile floor, like a business. There is a "No Oil" on the blue tape on the plate. After building an engine, I would put oil in it to try and start it to see if everything is correct before I would take it straight to Uncle Franks to dyno it. Maybe that's just me, I could be wrong.
After Uncle Frank's build it, you had to pay them to tune it for you. So you had them do the whole package while you was in his shop. Another clue is if they didn't have a printer, then how did they print you an invoice? Oh, I know, it's not connected to the dyno and a well respected business won't have a printer connected to their dyno.
