You have a ... '77 cb760 motor and carbs?('78 mabey?)
Will a set of earlier cb750 carbs fit your motor and carb isolators?
I bought a '73 set of cb750 carbs for my 650, and got the choke engagement on the side of the carb, no cable involved, all mechanical linkages. kinda of a pain to set right, but works great once set.
