Hey im having problems tuning my car. I have my idle set good. but sometimes i bring it to a complete stop the the car idles really high but other times i bring it to a stop and it idles normal. The carb is all the way closed, im sure of that. It also will run good for like 2 minutes than it goes weird again. Does this sound like an air leak. I got the carb, backplate, the carb bolt, And the little rubber thing on the carb sealed off. I dont know whats going on. Any help would be appreciated. Thank you.
