Small Engines (Lawn Mowers, etc.): Timing a overhead velve small engine, honda gc160, horizontal shaft

Question
I have a Honda GC160 5HP horizontal shaft engine with overhead valves and a timing belt. I had to change the intake valve. After I got the piston back in I realized that I forgot to mark the timing gears. I can't find any marks on the crankshaft gear or the black plastic camshaft gear on the top. How do you time an engine like this? Any help would be greatly appreciated. Thank you, Mike Lancaster
