Test Equipment
- The equipment required for testing includes: tachometer, hand vacuum pump, digital volt-ohmmeter (minimum 10 megohm impedance), and jumper wires.
- Before beginning any of the tests, a clear air cleaner cover must be fabricated from plastic at least .25" thick. This is secured by the air cleaner wing nut after the top of the air cleaner has been removed to observe operation and position of metering pins. See Fig 1 .
NOTE:
The metering pins operate in tandem. Only the upper pin is visible.
