Does anyone know which was the old Alis that had 2 fuel tanks? It had spark plugs but it could run on gas or kerosene. The intake and exhaust manifolds were all in one. the small tank was for gas, the big tank was for kero. it started in gas, and once it got warmed up good you opened the kero valve and then closed the gas valve. the kero ran around the exhaust before it went in the intake via the carb. It was heated till the flash point was at least as good as regular gas. Heck, it would run on melted lard, as good as gas, or motor oil, just about any type of petroleum product, or animal fat. I sure would like to know the model number, etc. I always thought it was a WD45.
