Hi, I just installed a 1977 400 in place of my worn out 305 in a k10, I fired truck up for 1st time today but the elec choke never opened up ,has 12 volts to choke, had to hold flaps open in order for truck to stay running, the carb part number is 17086226 0463 fkc. My question is do all electric choke models have a front vacuum pullback , mine has nothing, am I missing this, there are 2 screw holes on front and top of carb.
