I have an 82 civic. The sticker on the hood says the motor is a 1.5. It's not a cvcc car. I'm changing to a weber carb. According to the parts lists I can find it's listed as 197x-1983 1.2 and 1.5, 8 valve non cvcc being the only application for it. Here's the problem, the motor has the keihin 3barrel and 12 valves. The only casting number I can find on the block is HmS2 2F23. Can anyone tell what motor I have so I can get the correct adapter plate?
