switch base from q/jet to q/jet ?

[bober]

I'm sure this is on here somewhere ; Can I swap the base of one carb to another ? I'm starting a rebuild on a17080272 q/jet and if I need a new or diff base is there a chance that I'd be able to swap w/anothe q/jet ? I've got access to others for parts or whatever ? Thanks !!

 There were a lot of emission parts on the later Qjets, but don't know if that would have any effect. Try looking for a Qjet around the same year. Notice there might be slight differences in the linkage.

Many will fit, but there are quite a few different things going on with them, including vacuum ports, bypass air, idle fuel discharge holes, etc.  Best to match them  up exactly, or use one from the same carburetor number.....Cliff
