I'm not sure which connector your'e referring to above, but a picture of that connector along with your new carby would be good.
AFAIK, these aftermarket Nikki identical carbies don't come with a sight glass to see the float level. If that's the case, I would advice you do swap over the one from the old one into the new one, so you can see the float level and adjust it to suit your particular engine.
