Rochester carb swap question

I just swapped in a Rochester carb onto the 258 in my CJ and have a question for anyone else that has done this swap. What do you do with the lines that used to go to the charcoal cannister? There are two smaller line and one larger hose. Do you just skip the cannister? I just finished the swap so I haven't driven it yet but it idles fine. I hooked the pcv line to the larger port on the back of the carb and the vacuum advance to a port in the front just under the fuel bowl, is that right? To set the mixture screws on the front of the carb you set your idle and then turn them in till it stumbles and the back our 1/4 to 1/2 turn? Thanks for any help.

Re: Rochester carb swap question

Sounds like you're on the right track. I just capped the extra hoses that didn't connect to the carb. Mine runs great like that! You've got the Air mixture adjustment right, but it should be close if you bought the rochester new. Good luck,
