How do you set the timing on a 76 Chevy 350?

Answer 1

# Disconnect and plug the vacuum line that connects to the vacuum advance diaphragm on the distributor. # Loosen the locking bolt at the base of the distributor that allows it to turn freely, but don't turn it yet. # Connect a good quality timing light, the kind with an EXTERNAL power source, either plugs into the wall outlet or connects to the vehicle battery. # The engine has to be timed close enough to start which requires a little knowledge and experience. # Start the engine and point the timing light at the timing mark on the dampener pulley. # Turn the distributor (where you loosened it) until the timing mark aligns with the appropriate advance mark as specified in the manual. The advance may be slightly different for YOUR altitude. # Once the timing is where you want it, turn off the engine and tighten the distributor lock bolt, then restart the engine to make certain the timing is still right. # Disconnect the timing light and reconnect the vacuum advance line.
