we carbed a 13b and put it in a 12a chassis. now we have the right carb on it cuz i checked its a 6 port motor and we put a 650 carb on it. it accelerates fine and gas isnt the problem but i think its not idled high enough cuz it cuts off when we let the motor idle. does anybody know if im right?

 

any updates? I'll be carbing an s5 this week to drop in a fb.
