I’ve been driving my 1965 C10 truck for approximately 800 miles with the same Rochester 2Jet mounted on an original cast iron two barrel manifold on a 283 SBC. This weekend I had trouble getting the engine to run and idle. A look under the hood showed fuel spilled onto the manifold. I decided spark was good so I tore down the carburetor and found the float was partway filled with fuel. It must have a pinhole somewhere. My parts drawer had a spare float, but it did not look EXACTLY like the original. The float was the same but the arm was slightly different. I installed the float, and the truck is up and running just fine. Nothing seems wrong at all and no more fuel spillage onto the manifold. I have no idea how old the float is that I just installed. So I ordered another float which arrived today. It looks identical to the one that is currently in the carburetor and working fine. I will assume that the float arm has different designs. The float is exactly the same shape and size. Here are some pictures. Should I have any concerns?
