Fuel Level (Wet)
Fig. 6 Fuel level adjustment:
1. Operate engine to normalize engine temperatures, and place vehicle on a flat surface as near level as possible. Stop the engine.
2. Remove air cleaner, then remove carburetor air horn and gasket.
3. Temporarily place air horn and gasket in position on carburetor main body and start engine.Let engine idle for a few minutes, then remove air horn and gasket to provide accessibility to float assembly.
4. While engine is idling, use standard depth scale to measure vertical distance from top of machined surface of carburetor main body to level of fuel in bowl, Fig. 6. Measurement must be made at least 1/4 inch away from any vertical surface to insure an accurate reading, because the surface of the fuel is higher at the edges than in the center.
5. If an adjustment is required, stop the engine and bend the float tab as necessary to bring the fuel level within specifications.
6. Each time an adjustment is made to the float tab to alter the fuel level, the engine must be started and permitted to idle for at least three minutes to stabilize the fuel level. Check fuel level after each adjustment until the specified level is achieved.
7. Assemble carburetor with a new air horn gasket. Then adjust idle speed and mixture, and anti-stall dashpot, if so equipped.
