Got a 185S with a carb that doesn't match the books

Bought a 185S and while I got it to run, it was real rough, rich. Looked at the carb and it doesn't match what the book says it should be. It has a 26 on a stamping, nothing on the bottom and the bottom has a spring clip holding the bowl on instead of the 3 screws. Main jet has 130 stamped on it and the 185S is suposed to be 95. I think like I need to do a rebuild on it but would like to identify which carb I have. Any Ideas???

can you tell if its a keihin or mikuni?

It's a Keihin. The choke is not a butterfly but a slide shutter. While the inlet and outlet dia is the same as stock, the throttle body tube is oval with a cylinder shuttle and the slide chole in front.
