How To Find Top Dead Center For Timing

Postby Gary Dotson » Wed Jan 19, 2011 8:34 am

Observing valve function is my favorite method of locating top dead center, for ignition timing purposes. I don't watch the valves on #1, however, but #4. As the piston approaches TDC. the exhaust valve is closing and just it reaches TDC, the intake valve will start to open. I stop at that point & align the timing mark. That's TDC on #1 cyl. It's easy & totally fool proof.
