Initialization Check
- While observing metering pins, have helper turn ignition switch to "ON" position. Metering pins should move fully toward front to vehicle, reverse direction and move partially toward rear of vehicle. They should then stop for approximately 40 seconds and then move in either direction.NOTE: Metering needles work in tandem. Only 1 needle will be visible in carburetor.
- If pins do not move after 40 seconds, check vacuum hose routing or replace CTO and continue diagnostic checks. If pins fail to move at all, perform Initialization Test sequence.NOTE: Switch colors referred to in Checks and Tests are color of switches lead wire.
