If you have to have 2 oper. chokes,you might be able to do it this way.Seeing you have cable choke levers,you could buy a pc. of heavy piano wire approx diam of the orig. cable[inner pc] and double up on the ends that go into the rear carb lever.Even if you have to enlarge the wire hole slightly on the rear one then run the added wire pc for the front carb to the front lever. It might work.Worth a try.Other wise i wouldn't wory about only having 1 choked carb.Wire tie the non oper. choke so it dosen't close on you. ken ct.
