I have a 67 GTO, 400 engine. The quadrajet has the number 8905 1902 stamped on the side. The choke linkage is not correct on this carb. The choke stove spring pulls in the wrong direction and keeps the choke open all the time. Does anyone recognize what carb is on this engine? It looks to be brand new, but is incorrect to work with the Pontiac style choke spring in manifold.
