Ignition Timing
CAUTION:
Timing light connections should be made using proper adapters. Do not puncture cables, boots or nipples with test probes.
NOTE:
Engine is equipped with a magnetic probe receptacle, located 10° ATDC. Do not use this location to check timing with a conventional timing light.
Ignition timing is checked with engine warm and idling. Vacuum hose should remain connected to computer on air cleaner. Use a jumper wire to connect carburetor idle stop switch to ground. Connect timing light and adjust timing by turning distributor.
