i have a 76 pontiac carb ( well at least thats what the numbers decoded to be, however, idk how accurate that is becauase it also said the carb was a 2 barrel 2 jet, when its definitely a 4 barrel) BUT yes, it is a hot air choke. so how hard is it to add on the electric choke? also it says that my carb was for a California emission standard, does that take anything away from performance? is there anyway to tell how much cfm it is? i have a mild cam in the engine (did not know when it was purchased) and i want to make sure im getting enough air to it. Thanks for the help guys, kyle
