Air jets where the mixture screws go... is this a thing?

[Guest]

So I got a set of carbs on ebay but this has me scratching my head. It was dirty and in pieces; I didn't expect much. The spot where the air jets go is plugged and the air jets are where the mixture screws are supposed to be. Is this like a dyno jet thing... or something? needles don't look stock and aren't marked, looks like some amature drill marks on the slides, mains say 170 and look like the 'small round' kind not the stock kind... just trying to figure out what I'm looking at here.

A picture would help us a lot

Well, in answer to your question: No. There's no reason it should be like that. Nonetheless, I'd really like to see a picture of this.

Yeah. It looks to me like he switched the holes they should go in. I'd take them out and order some new parts, or send them back. That "plug" looks like the mixture screw.

I bought it for the needle jets / needles, the rest is spare parts as far as I'm concerned... baffling though huh?
