Is there any stamps or a way of identifying copycat Chinese carbs? I don't see Keihin stamped anywhere, I also see differences with the screws that hold the cover to the vacuum diaphragm that lead me to believe it is a Chinese copycat.

The choke inlet is what has me totally confused, it doesn't have to pressed in brass fitting like in the pic you posted, the inlet on mine is threaded and had a 5mm rounded jet threaded into that spot.(identical to the main jet BUT stamped with 0.65). This is obviously completely wrong right? I'll post a pic I took directly after taking the floats off that I was going to use as a reference when reassembling it until I noticed all of this lol.

I guess if they are copycats I will have to track down
some Keihins carbs and possibly a stock air intake. In the mean time is there any advice on what I can do to make these useable until I can track a stock one down?
