Does anyone know what the intake tube/exhaust box around the exhaust manifold is called. It's missing from my 1928 4 cylinder and I would like to try and buy or make one. From all I have read in the forums these engine like warm air to run on. I attached the only photo I could find. This view is from the passenger side. I think the other side has a tube that connects to it and run across to the inlet of the carburetor.
The enlarged area around the exhaust pipe is called the stove. Yes the other side has the outlet which connects to the flexible metal hose that supplies warm air to the carburetor. That warm air helps to vaporize the gas droplets formed in the carburetor. Only vaporized gas burns well in the engine. Droplets mainly form carbon instead of energy.
