On this type of heater there is a "carburetor", which is a misnomer. It is simply a constant level device. The float mechanism keeps the level of fuel constant, as the level of fuel in the tank varies. There are typically several concealed adjustment screws under the top plate of the "carburetor". There is a float level adjustment, used to set the level of fuel to a level usually marked on the inside of the float chamber. There is an adjustment screw used to set the flow of fuel to the burner to a minimum that will keep the fire lit when the control knob is turned to it's lowest position. There is a high fire adjustment screw that limits the flow of fuel to the burner to a maximum rate, to keep the fire to a safe limit when the control knob is turned to "HIGH". Originally, there would have been a manual for the stove, listing the drops of fuel per minute for HIGH and LOW fire. (Rates would may have been given in CC's, in some cases.) These stoves are not the safest devices ever made, and I am not in any way suggesting you mess with it. I am simply stating how they worked in the "old days". If the "LOW" firing rate is set too low, the "pot" will get too cool, and the fire will go out. NEVER attempt to re-light one of these stoves that has gone out, while it is still warm. The oil vapor may explode. These stoves were made to burn kerosene. #1 fuel oil normally will not work as well, and #2 fuel oil probably won't work at all.
