Has anyone put a new carb on a 77 Bat VA?? I bought this SHA 12/12 one on ebay and its not going to work because of the choke lever... If any one has put a new carb on a 77 VA, I would like to know exactly what you used and what had to be done. I see the ones listed on treatland that are "compatable" for the laura engine but they all seem to have the same choke set up?
