If you can't fix it with a hammer, you've got an electrical problem. Using a timing light you can verify the distributor mechanical advance is working. You are also correct on the timing marks - the first mark is 16 degrees BTDC and the second mark is TDC. Furthermore, this tool allows you to measure this highlight in degrees. You can also use it the same way to check mechanical advance by just revving the engine. Then read the will tell you the advance. The light from this device will pulse with a strobe effect and highlight what your timing is. with engine idling.just point the light at the pointer/damper, then turn the dial on the light until the line on the damper lines up with the 0 deg mark (or TC) on the damper.

Modern electronically controlled passenger vehicle engines require use of a scan tool to display ignition timing. A timing light is an engine diagnostic and tuning tool that allows you to check the timing of your vehicle’s spark plugs. A timing light is a stroboscope used to dynamically set the ignition timing of an Otto cycle or similar internal combustion engine equipped with a distributor. Now, with a dial-back light, and the engine at 3000rpm, turn the dial clockwise and you'll see the timing mark on the balancer "retard" and move closer and closer to the 0-degree mark on the timing tab. A timing light is an engine diagnostic and tuning tool. Patented skip circuitry tests up to 9990 RPM, delivering precise analysis to ensure that vehicles operate at maximum efficiency. For checking: 1.Injection pump timing under operating. Chances are your timing mark is way beyond the 12 degrees or so of your timing "tab" (the degree marker mounted to the front cover). A technician can use this helpful tool to read a diesel engines timing and do any necessary adjustment. How to use a timing light Attach the clip over the ignition output between the ECU and the ignition module Remove a single coil on plug setup from the engine. With a conventional light, in order to check total timing, you'd disconnect the vacuum advance, rev the motor to 3000rpm (that's usually fast enough to ensure the distributor timing is maxed out), and you'd pull the trigger to check timing. A dial back light delays the strobe light in the amount of the # of degrees on the dial.
