THE CARBURETOR
Touching the primer of the carburetor will show whether the gasoline flows to the float chamber, for if it is present it will spurt out of the opening through which the priming stem passes. If the air inlet is so arranged as to permit it, gasoline dropping out of it when the carburetor is primed excessively indicates that the liquid flows out of the spray nozzle, this part thus being shown to be clear. If no gasoline shows around the priming stem, the feed pipe or float valve may be suspected of being clogged, it being taken for granted that there is gasoline in the tank and that the supply cock is open. If it is found that gasoline is present in the air inlet, and that the carburetor is damp with it when the primer has not been touched, it indicates that the float chamber is flooded; the carburetor should be taken apart for inspection and thorough cleaning.
