NENKUTEN 1 Barrel Carburetor for Rochester 235 Engines 1957-1961 Chevrolet GMC Chevy Truck 3.8L 3852CC 235Cu 6 Cly Engines Automatic Choke Nomad Bel Air El Camino with Replacement throttle arm 7009657

The carburetor is not a direct fit, it does not have the same type, piping or thread as American made. In fact, I have no idea what type of thread is on it. The heat riser pipe tube does not work from the original carburetor to the replacement. In order to make this work for my application I had to remove the base plate from the original Rochester carburetor and install it on this new offbrand replacement once I have done that I was able to get it to work properly

This does not come with tube located on left side of carb. I was unable to locate part needed. Why is tube not installed on the carb? I already have a carb I cannot return for the same reason and do not need another
