Test Equipment

The test equipment required to perform the tests include: Tachometer, hand vacuum pump, digital volt-ohmmeter with minimum 10 megohm impedance and a No. 158 bulb with socket and jumper wire.
Before beginning any of the tests, a clear air cleaner cover must be fabricated from clear acrylic plastic at least 0.25" 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.
