Troubleshooting
Troubleshooting can be difficult. On the following pages there is a list of possible problems. To make a repair to a problem, make reference to the cause and correction.This list of problems, causes and corrections, will only give an indication of where a possible problem can be and what repairs are needed. Normally, more or other repair work is needed beyond the recommendation in the list. Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts. This list can not give all possible problems and corrections. The serviceman must find the problem and its source, then make necessary repairs.Troubleshooting Problem List

Low Idle Adjustment Procedure
Use the 6V3121 Multitach Group or the 1U6602 photo tachometer to accurately measure the engine low idle rpm. DO NOT use the instrument panel tachometer to set engine low idle. Use this procedure any time the low idle rpm is changed, even slightly.
Governor (Typical)
(1) "Standard" Low Idle Adjustment Screw. (2) "Buffer" Spring Adjustment Screw.1. Start the engine and allow it to warm up to operating temperature and allow the low idle reading to stabilize. Low idle readings should be taken after snapping the throttle open about 1/3 of its travel, and releasing it quickly. This will help insure the governor control is in its natural low idle position against the "standard" governor low idle screw (1).2. Turn the "buffer"
