fuel consumption idleing?

[H. L. Chauvin]

1. Open gas line, then close gas line.

2. Start car & allow engine to run until it uses up gas this amount of gas in carb & gas line.

3. Repeat step one, omit step 2., loosen fitting at sediment bulb to brake the vacuum effect, & remove drain plug at bottom of carb, & allow to drain in a measuring cup.

4. Convert ounces to gallons -- should give a "rough" idea of gallons per hour at idling with "no"' load on engine.
