should the valves be open at top and bottom dead center alternately
Make: briggs and stratton
trying to find timing mark on valve cam gear.
Hello and welcome to Just Answer,
The valves will be open near TDC. As for the timing marks, the Briggs are one of the easier ones. The camshaft gear has a dot or dimple on the gear. The crank gear has the same dot or dimple. Just line the 2 marks up and it is in time.

the cam gear does not have a dot but the gear has a slot indented on one part doesthis align with the dot on the crankshaft gear?
That should be it.
