Timing Check

Disconnect grounded jumper wire from self test input. Start engine and reconnect grounded jumper wire to self test input. Check timing. If timing is 27-33° BTDC, proceed to Engine Running Test. If timing is not 27-33° BTDC, proceed to Spark Advance Test.

NOTE: If engine stalls while testing, proceed to Symptom Diagnosis Test.
