So, i recently bought my first Mustang, a 1964 1/2 (Originally a 170 but now has a 200 from a 1966 Falcon i believe). The previous owner did not know much about cars so i think im mainly fixing his screw ups. The car currently has a different carb on it and im not sure what model it is, but was hoping someone could identify it in the pictures, because it seems to run pretty rough with whats on it and ive heard that these 200's are picky about there carbs. Ive also heard that this engine should have the Load-O-Matic distributor in it, and im not sure that it does. If someone could tell me if i do from the pictures that would be great. I do have what the owner thought was the original carb, but it appears to be a 1969 carb because it does not have the vent rod or the spark control valve. So my question is, would i be better off switching to this other carb since it is more original, even i have the load o matic and not the SCV? Or should i stick with whats on there and see if i can tune it in? Knowing what carb and distributor are currently on it would be a great help.
