Small Engines (Lawn Mowers, etc.): Setting timing on Honda HRR2164VXA mower, alignment marks, cam points

Question
Eric,

This is a follow-up to a question answered by Ben.  I replaced the crankshaft on my Honda HRR2164VXA, S/N MZCG-7750581 and now need to set the cam pulley/crankshaft timing correctly.

The number dotted on the engine is GJAEA 5863716, I believe the type is GVC160A MU4 R280.  

Ben sent an image that refers to alignment marks on the cam pulley.  I pulled the head cover, but was unable to identify these marks on the pulley.  Could you tell exactly what these alignment marks look like and where they are located in relation to the cam (i.e. if the the cam "points" to 12 o'clock, at what time should I see the marks).

Any other pointers on correctly setting the timing are greatly appreciated.

Thanks!

Answer
If you have not removed the camshaft you can rotate the crankshaft until the piston is at top-dead-center (TDC).  At TDC the piston will be at the top of the cylinder.  Look for lines, dots and other distinctive marks on the camshaft and crankshaft timing gear.  If you do not see any marks rotate again until TDC.  Look for timing marks.  If you still do not see any marks you can use a scribe, punch or even a screwdriver to scratch some marks on the crankshaft and camshaft.

Let me know if this helps.
