Valve Timing Mark for Intek 31

Briggs Intek engines require that the valves be set with the piston 1/4" past TDC on the power stroke.

I had one apart so while I was there I filed a timing mark on the flywheel with the piston at 1/4 inch past TDC.

 First I positioned the piston.
The I used a file to mark the flywheel using the edge of the magneto as an indicator.

This has to be more easier and more accurate than stuffing a screw driver down the spark plug hole.

The one drawback is that the magneto is not fixed.  On this particular engine there is not enough play in the bolt holes to matter.  But one could always set the flywheel to the mark when working with the coil.
