  1. Locate idle compensator in air cleaner. Apply vacuum to idle compensator air tube. If idle compensator leaks, replace idle compensator assembly.
  2. Check that idle compensator is closed when bimetallic valve temperature is lower than operating temperature. Valve opening temperature should be 141-157°F (61-69°C). When bimetallic valve temperature is more than 157°F (69°C), valve should be open. If not, replace idle compensator assembly.
