To get home, take out the small plug at the top of the tank and fill with gasoline. It holds about a quart of gas, and will run the average car about four miles. If the engine stops before you reach home or a Service Station, you will have to fill the Tank■gain as before.NOTE—If you happen to run completely out of Gasoline on the road, »nd fill up the main tank, it is NOT necessary to prime the Vacuum Tank or the Cartmretor. ^Just close the throttle and turn the engine over with the Starter a few times, when the gasoline will soon be drawn through Into the Vacuum Tank, and the engine will startrpo-■ars. ft on dorsIIIF THE STARTING MOTOR TURNS THE ENGINE OVER ALL RIGHT, AND THE GASOLINE COMES THROUGH FREELY TO THE CARBURETOR then— 1* m1.
