I have a 1953 3100 ½ ton truck with its original 216 engine. Carburetor is a Rochester “B”, also original to the truck, with the thicker top flange first introduced in the 1952 model year. The truck will not start unless I either use starting fluid (which I don’t like to do) or manually fill the float bowl with fuel. With fuel or ether, it starts right up, and runs great. This condition exists when the truck is cold, as well as when it has been run but has been sitting for any amount of time.

I have read up on the “usual” issues with these things, and have addressed them as follows:

Starter. Spins pretty well with an Optima 6-volt battery providing juice.

Starter cables. Heavy ("0" gauge). Custom made from welding cable.

Timing. I have it set per spec, to the point that it neither bogs nor spark-rattles.

Carburetor. Rebuilt by the premier Rochester specialist in the VCCA. Phenolic spacer is installed. Mixture adjusted with exhaust gas meter.

Fuel. I have been using strictly non-ethanol gas since I put the truck together, about 5 years ago.

Manifold heat valve. I have it wired shut, i.e. no hot air from exhaust manifold toward intake.

Running temperature. Temp gauge stays at 180, as it always has.

I can’t believe these trucks acted like this when they were new – otherwise, Chevrolet couldn’t have sold as many as they did in the 1950s.

Any ideas? I’ve been working on Chevrolets for 40 years, but never one this old, and it has me stumped. I would be grateful for any help.
