Small Engines (Lawn Mowers, etc.): Lawnboy GVC 160, crank shaft, cam shaft

Question
gjaea-2561662 on replacing the crank shaft and the cam shaft is turned where does the cam shaft have to be to get the timing right?  Do both valves have to be closed or does the intake or exhaust have to be open?

Answer
There is an arrow on the crankshaft lobe that should line up with a mark running down the center of the engine and points towards the came lobe gear. The black cam lobe gear sticks about a 1/4 of the way out from under part of the engine block that the valve stem actuators are attached to. There are two timing marks on top of the black cam gear in the form of lines that point towards each other. These two marks line up with the edge of the block that the gear is sticking out from underneath. Make sure you put the big flat washer back on top of the belt on the crankshaft after the belt goes on.

You can Google Honda GVC 160 timing, valve timing, camshaft timing and you will find a decent amount of information.

Let me know if this helps.
