Test Equipment

  1. The equipment required for testing includes: tachometer, hand vacuum pump, digital volt-ohmmeter (minimum 10 megohm impedance) and a jumper wire.
  2. Before beginning any of the tests, a clear air cleaner cover must be fabricated from clear plastic at least .25" thick. This is secured with air cleaner wing nut after top of 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.
